how to book reliance jio mobile phone for free

Reliance Jio announced the launch of the Jio Phone at the annual Reliance Industries AGM on Friday. The effective price of the phone is zero - you need to pay a Rs. 1,500 deposit up front, which is refundable after three years. Jio Phone users can enjoy Reliance Jio services like free voice calling and SMS, as well as access to Jio apps like JioTV and JioMovies at Rs. 153 per month, Reliance Industries Chairman Mukesh Ambani said. This Jio plan also gets you 'unlimited' Internet data, with a daily high-speed data cap of 500MB.

So is the Jio Phone going to be the phone that gets the next set of Indians on the Internet? What are its limitations? Does the Jio Phone run WhatsApp? Read on for the answers to these, and other questions.

Jio Phone launch date and booking

The Jio Phone will be made available starting August 15 in a beta programme, and it will be up for pre-booking from August 24 onwards. Pre-orders can be made using the MyJio app or Jio offline stores. Customers who pre-book the phone will be eligible to purchase it from September onwards, on a first come first serve basis. Mukesh Ambani said Jio is targeting to have 5 million Jio Phones available every week.

Jio Phone cable TV and plans

There are two prepaid plans that you can sign up to with the Jio Phone. Both have a one month (28 days) validity, and include 'unlimited' data, unlimited calling, and SMS. The plans are for Rs. 153 and Rs. 309 respectively, and on the surface look very similar, but there's one difference. With the Rs. 309 plan, users will be able to use the Jio Phone-TV cable to mirror their phone screen onto any TV, so that Jio's streaming services can be enjoyed by the whole family. The Rs. 153 plan come with 500MB daily FUP for the high-speed data.

At the same time, Ambani also noted that for users who don't want to commit to a monthly plan, Reliance Jio also has a couple of sachet plans that give shorter term access to data. For two days, Jio Phone users can get the Rs. 24 pack, or they can opt to spend Rs. 54 for a week of usage. Note that these plans are exclusive to Jio Phone users and cannot be subscribed by other Jio users.

Jio Phone features and price
Introduced as "India ka smartphone", the Jio Phone will be effectively free. Of course, it's not quite as simple as that - you will have to make an upfront payment of Rs. 1,500 in order to get your hands on the Jio Phone. However, this sum is fully refundable, but you can claim the refund only after three years of purchasing the mobile.

ALSO SEEWhat is the Jio Phone TV-Cable?

In his AGM speech, Reliance Chairman Mukesh Ambani pointed out the majority of phone users in India do not have smartphones, pegging the figure at 50 crore (out of 76 crore mobile phone users). Because of the high smartphone prices, they are unable to access the 4G-only Jio network, meaning not only are they unable to get access to high-speed Internet and free voice calls, but also that they are out of Jio's reach as a monetisation opportunity. The Jio Phone is meant to address this audience, and thus is an affordable, 4G VoLTE-capable feature phone with 'smart' apps.

Yes, the Jio Phone's got all of the Jio apps - that means Jio Music, Jio Cinema and so on, and access to these is bundled with the prepaid plans for the phone, so even on a feature phone you'll be able to enjoy streaming services. It supports other apps as well, including Facebook, though WhatsApp is not supported at the moment. The phone also supports 22 Indian languages, and voice commands. You can send messages, place calls, search the Web, and so on, using voice commands.

Another interesting feature of the Jio Phone is NFC support - with this, users will be able to make payments from a linked bank account via UPI, or through POS machines in place of a debit card. This will be enabled later via a software update, although the hardware is already present. The mobile also comes with an integrated panic button.

Jio Phone features revealed at the Reliance AGM

The Jio Phone will also be able to mirror content from apps such as JioTV and JioCinema on TVs (including old CRT TVs) using a cable that the company has developed. Users will need to subscribe to the Rs. 309 Jio pack to avail this feature.

While company went in detail regarding the features, there was not as much focus on Jio Phone specifications. As a feature phone, the device has an alphanumeric keypad, and a small 2.4-inch colour screen. Apart from the presence of a rear camera, FM radio, Bluetooth, NFC, and of course 4G VoLTE, not much is confirmed at the moment.

Time and speed

Welcome to aptitude tricks

Problems involving Time, Distance and Speed are solved based on one simple formula.

Distance = Speed * Time

Which implies →

Speed = Distance / Time   and

Time = Distance / Speed

Let us take a look at some simple examples of distance, time and speed problems.

Example 1. A boy walks at a speed of 4 kmph. How much time does he take to walk a distance of 20 km?

Solution

Time = Distance / speed = 20/4 = 5 hours.

Example 2. A cyclist covers a distance of 15 miles in 2 hours. Calculate his speed.

Solution

Speed = Distance/time = 15/2 = 7.5 miles per hour.

Example 3. A car takes 4 hours to cover a distance, if it travels at a speed of 40 mph. What should be its speed to cover the same distance in 1.5 hours?

Solution

Distance covered = 4*40 = 160 miles

Speed required to cover the same distance in 1.5 hours = 160/1.5 = 106.66 mph

Now, take a look at the following example:

Example 4. If a person walks at 4 mph, he covers a certain distance. If he walks at 9 mph, he covers 7.5 miles more. How much distance did he actually cover?

Now we can see that the direct application of our usual formula Distance = Speed * Time or its variations cannot be done in this case and we need to put in extra effort to calculate the given parameters.

Let us see how this question can be solved.

Solution

For these kinds of questions, a table like this might make it easier to solve.

Distance	Speed	Time
d	4	t
d+7.5	9	t

Let the distance covered by that person be ‘d’.

Walking at 4 mph and covering a distance ‘d’ is done in a time of ‘d/4’

IF he walks at 9 mph, he covers 7.5 miles more than the actual distance d, which is ‘d+7.5’.

He does this in a time of (d+7.5)/9.

Since the time is same in both the cases →

d/4 = (d+7.5)/9            →        9d = 4(d+7.5)   →        9d=4d+30        →        d = 6.

So, he covered a distance of 6 miles in 1.5 hours.

Example 5. A train is going at 1/3 of its usual speed and it takes an extra 30 minutes to reach its destination. Find its usual time to cover the same distance.

Solution

Here, we see that the distance is same.

Let us assume that its usual speed is ‘s’ and time is ‘t’, then

Distance	Speed	Time
d	s	t min
d	S+1/3	t+30 min

s*t = (1/3)s*(t+30)      →        t = t/3 + 10      →        t = 15.

So the actual time taken to cover the distance is 15 minutes.

Note: Note the time is expressed in terms of ‘minutes’. When we express distance in terms of miles or kilometers, time is expressed in terms of hours and has to be converted into appropriate units of measurement.

Welcome to aptitude tricks
Question 2 - A is twice as efficient as B and can complete a job 30 days before B. In how much they
can complete the job together?
Solution - Let efficiency percentage as x
A's efficiency = 2x and B's efficiency = x
A is twice efficient and can complete the job 30 days before B. So,
A can complete the job in 30 days and B can complete the job in 60 days
A's efficiency = 1/30 = 3.33%
B's efficiency = 1/60 = 1.66%
Both can do 5% (3.33% + 1.66%) of the job in 1 day.
So the can complete the whole job in 20 days (100/5)
Question 3 - A tank can be filled in 20 minutes. There is a leakage which can empty it in 60 minutes.
In how many minutes tank can be filled?
Solution - Method 1
⇒ Efficiency of filling pipe = 20 minutes = 1/3 hour = 300%
⇒ Efficiency of leakage = 60 minutes = 100%
We need to deduct efficiency of leakage so final efficiency is 200%. We are taking 100% = 1 Hour as
base so answer is 30 minutes.
Method 2
⇒ Efficiency of filling pipe = 100/20 = 5%
⇒ Efficiency of leakage pipe = 100/60 = 1.66%
⇒ Net filling efficiency = 3.33%
So, tank can be filled in = 100/3.33% = 30 minutes
You can change the base to minutes or even seconds.
Question 4 - 4 men and 6 women working together can complete the work within 10 days. 3 men
and 7 women working together will complete the same work within 8 days. In how many days 10
women will complete this work?
Solution - Let number of men =x, number of women = y
⇒ Efficiency of 4 men and 6 women = 100/10 = 10%
⇒ So, 4x+6y = 10
Above equation means 4 men and 6 women can do 10% of a the job in one day.
⇒ Efficiency of 3 men and 7 women = 100/8 = 12.5%
So, 3x+7y = 12.5
By solving both equations we get, x = -0.5 and y = 2
⇒ Efficiency of 1 woman(y) = 2% per day
⇒ Efficiency of 10 women per day = 20%
So 10 women can complete the job in 100/20 = 5 days

Time and work 7

Welcome to aptitude tricks
Example 2: If a person can complete his work in 5days. What will be his efficiency?
Solution: Number of days a person take to complete his work = 5
⇒ He is doing 1/5 th work per day (converted into fraction)
Convert it into percentage:
100/5 = 20%
Therefore, his efficiency is 20%.
Summarizing, If a person can do his job in n days, efficiency will be
Efficiency = %
Note: Negative efficiency cancels the positive efficiency
For Example: Positive efficiency = 5%
Negative efficiency = 1.5%
Net efficiency = 5- 1.5 = 3.5%
As we all know, in competitive exams time management is very important. I suggest you to learn the
fractions till 15.
Number of days required to
complete work
Work/Day Efficiency (%)
N 1/n 100/n
1 1 100
2 1/2 50
3 1/3 33.33
4 1/4 25
5 1/5 20
6 1/6 16.66
7 1/7 14.28
8 1/8 12.5
9 1/9 11.11
10 1/10 10
11 1/11 9.09
12 1/12 8.25
13 1/13 7.69
14 1/14 7.14
15 1/15 6.66
Example 3: A can do a job in 10 days. B can do a job in 5 days. In how many days they can complete
the job if they work together?
Solution: Consider the above table
A's efficiency = 10%
B's efficiency = 20%
A+ B efficiency = 10 + 20 = 30%
This means, In one day A and B together can do 30% of work.
Therefore, Number of days A and B together take to do 100% of work =
⇒3.33 days

Time and work

Welcome to aptitude tricks
Chapter - 12
Time and Work
Three main factors of Time and Work
There is a definite relationship between Time and Work. In this concept, there are only three factors:  Time taken to complete a certain job
 Unit of work done
 Number of persons doing the job
There is a mental relationship between these three, discussed as follows:
Work done (W) = Number of days (Time taken) (T or D) × Number of men (M)
W = D × M
Some basic points
More number of men can do more work i.e. both are directly proportional
More number of men take less time to complete certain job i.e. both are inversely proportional
By summarizing, we get = ×
Let us start solving some examples:
Example 1: 10 men can cut 8 trees in 16 days. In how many days can 6 men cut 10 trees?
Solution: This is a very simple example. You are given:
W1 = 8
W2 = 10
M1 = 10
M2 = 6
D1 = 16
D2 = ?
Using formula, = ×
= ×
⇒D2 = 33.3
Concept of efficiency
This means, "How much work one person can do in one day (expressed in percentage)" For example: A person can do a job in 2 days
⇒ He can do 50% work in one day
Therefore, his efficiency will be 50%
Just a 2-step concept
This concept involves two steps to calculate efficiency:  Convert into fraction i.e. per day work
 Multiply with 100 i.e. convert into percentage

This topic is considered to be quiet important and every year a good number of questions are asked from this topic. We are providing you with Basic Concepts & Short Tricks to solve Clock related Questions in Reasoning which will surely help you in the upcoming SSC Exams 2016.

Clock

A clock is an instrument used for indicating and maintaining the time. It is an electronic device that present the duration of hour, minute and second.

Different types of question  covered in this chapter are as follows.

• Angle Between the Hands of clock
• Position of Hands of clock
• Faulty clocks
• Time Gained or lost by clock

The clock represents two things. i.e., minutes and hour. The minute is a unit of time equal to 1/60^th of an hour or 60 s i.r., 1 min = 60 s.

Clocks Concepts :

• The dial of the clock is circular in shape and was divided into 60 equal minute spaces
• 60 minute spaces traces an angle of 360⁰. Therefore, 1minute space traverses an angle of 6⁰
• In 1 hour, Minute hand traverses 60 minute space or 360⁰ ,Hour hand traverses 5 minute space or 30⁰
• The hands of the clock are perpendicular in 15 minute spaces apart
• The hands of the clock are in straight line and opposite to each other in 30minute spaces apart.
• The hands of the clock are in straight line when they coincide or opposite to each other.
• The hands of the clock are perpendicular to each other for 22 times in 12 hours and for 44 times in a day.
• The hands of the clock are opposite to each other for 11 times in 12 hoursand 22 times in a day.
• The minute hand gain 55 minutes over hour hand per hour.

Hence x minute space to be gained by minute hand over hour hand can be calculated as x.(60/55) or x.(12/11)

Ex : At what time between 2'O clock and 3'O clock the hands of the clock Ware opposite to each other.
1. 34( 6/11 ) past 2'Oclock

2. 43( 7/11 ) past 2'Oclock

3. 56( 8/11 ) past 2'Oclock

4. 64(9/11past 2'Oclock
Solution:

At 2'O clock the minute hand will be at 12 as shown below

The minutes hand to coincide with the hour hand it should trace at first 10 minute spaces and then the hands of the clocks to be opposite to each other minute hand should trace 30 minute spaces i.e. totally it should gain 10+30=40 minute spaces to be opposite to that of hour hand
We know that,
Minute hand gains 55 minute spaces over hour hand in 1 hour
Therefore, Minute hand gain 40 minute spaces over hour hand in 40 × (60/55) = 43(7/11)
Hence the hand of the clock will minutes be opposite to each at 43( 7/11 ) past 2'Oclock
Therefore, Correct option is 2'

When clock is too fast, too slow

• If a clock or watch indicates 6 hr 10 min when the correct time is 6, it is said that the clock is 10 min too fast. If it indicates 6. 40 when the correct time is 7, it is said to be 20 min too slow.
  Now let us have an example based on this concept

Ex: My watch, which gains uniformly, is 2 min, & show at noon on Sunday, and is 4 min 48 seconds fast at 2 p.m on the following Sunday when was it correct ?

Solution:From Sunday noon to the following Sunday at 2 p.m there are 7 days 2 hours or 170 hours.

The watch gains 2+4 ⁴/₅ min in 170 hrs.
Therefore, the watch gains 2 min in  (2  *170 * 5/34) hrs i.e., 50 hours
Now 50 hours = 2 days 2 hrs.
Therefore, 2 days 2 hours from Sunday noon = 2 p.m on Tuesday.
