Examples on "LCM method for time and work problems"

Example 1 :

A can do a piece of work in 8 days. B can do the same in 14 days. In how many days can the work be completed if A and B work together? 

Solution :

Let us find LCM for the given no. of days "8" and "14".

L.C.M of (8, 14) = 56

Therefore, total work = 56 units

A can do =  56 / 8 =  7 units/day

B can do = 56 / 14 =  4 units/day

(A + B) can do = 11 units per day 

No. of days taken by (A+B) to complete  the same work

= 56 / 11 days

Let us look at the next example on "LCM method for time and work problems"

Example 2 :

A and B together can do a piece of work in 12 days and A alone can complete  the work in 21 days. How long will B alone to complete  the same work? 

Solution :

Let us find LCM for the given no. of days "12" and "21".

L.C.M of (12, 21) =  84

Therefore, total work = 84 units.

A can do =  84 / 21 =  4 units/day

(A+B) can do = 84 / 12 =  7 units/day

B can do = (A+B) - A = 7 - 4 = 3 units/day  

No. of days taken by B alone  to complete  the same work

= 84 / 3

= 28 days

Let us look at the next example on "LCM method for time and work problems"

Example 3 :

A and B together can do a piece of work in 110 days. B and C can do it in 99 days. C and A can do the same  work in 90 days. How  long would each take to complete  the work ?

Solution :

Let us find LCM for the given no. of days "110", "99" and "90".

L.C.M of (110, 99, 90) =  990

Therefore, total work = 990 units.

(A + B) = 990/110 = 9 units/day  --------->(1)

(B + C) = 990/99 = 10 units/day  --------->(2)

(A + C) = 990/90 = 11 units/day  --------->(3)

By adding (1), (2) & (3), we get,

2A + 2B + 2C = 30 units/day

2(A + B + C) = 30 units/day

A + B + C = 15 units/day --------->(4)

(4) - (1) ====> (A+B+C) - (A+B) = 15 - 9 = 6 units

C can do = 6 units/day ,  C will take = 990/6 = 165 days

(4) - (2)====> (A+B+C) - (B+C) = 15 - 10 = 5 units

A can do = 5 units/day,   A will take = 990/5 = 198 days     

(4) - (3) ====> (A+B+C) - (A+C) = 15 - 11 = 4 units

B can do = 4 units/day,   B will take = 990/4 = 247.5 days

Let us look at the next example on "LCM method for time and work problems"

Example 4 :

A and B can do a work in 15 days. B and C can do it in 30 days. C and A can do the same  work in 18 days. They all work together for 9 days and then A left. In how many days can B and C finish remaining work?

Solution :

Let us find LCM for the given no. of days "15", "30" and "18".

L.C.M of (15, 30, 18) = 90 units 

Therefore, total work = 90 units.

(A + B) = 90/15 = 6 units/day  --------->(1)

(B + C) = 90/30 = 3 units/day  --------->(2)

(A + C) = 90/18 = 5 units/day  --------->(3)

By adding (1), (2) & (3), we get,

2A + 2B + 2C = 14 units/day

2(A + B + C) = 14 units/day

A + B + C = 7 units/day --------->(4)

A, B and C all work together for 9 days. 

No. of units completed in these 9 days = 7x9 = 63 units

Remaining work to be completed by B and C = 90 - 63 = 27 units

B and C will take = 27/3 = 9 days   [ Because (B+C) = 3 units/day ] 

Hence B and C will take 9 days to complete the remaining work.

How to cube a number faser

The cube of a number is that number multiplied by itself twice. For example, 5 cubed - denoted as 5³; is equal to 5×5×5 = 125. The technique for cubing any 2-digit number discussed below is based on the algebraic observation. 

Step-1:       Write numbers in a row of 4 terms in such a way that the first one is the cube of the 1^st digit, second one is the square of 1^stnumber multiplied by 2^nddigit, third one is the 1^stdigit multiplied by square of 2^nd digit and the fourth one is the cube of the 2^nddigit.

Step-2:    Write twice the values of 2nd and 3rd terms under the terms respectively in second row.

Step-3:        Add all the values column-wise and follow the carry over process.

Example: 


!)Find Cube of 14.

Step-1                             :        1³       1²×4   1×4²   4³

Worked-out row               :        1        4        16      64

Step-2                             :                  8        32     

Step-3                             :        Add the values column wise.       

Ex (12)^3 =. 1 2 4 8
                         4 8




Total =1728

Time and work part 1

Time and work:



method: Fraction Technique

A = 10 days i.e so work done in a day is 1/10^th.

2^nd Method: Efficiency Technique

Work done by a person in unit time is defined as efficiency in Time and Work Problems

A = 10 days so efficiency of A per day = 100/10 = 10%

1. Work from Days:

   If A can do a piece of work in n days, then A's 1 day's work =	1	.
   	n

2. Days from Work:

   If A's 1 day's work =	1	,	then A can finish the work in n days.
   	n

3. Ratio:
   If A is thrice as good a workman as B, then:
   Ratio of work done by A and B = 3 : 1.
   Ratio of times taken by A and B to finish a work = 1 :3

2.	A can lay railway track between two given stations in 16 days and B can do the same job in 12 days. With help of C, they did the job in 4 days only. Then, C alone can do the job in:
	A. 9 1 days 5 B. 9 2 days 5 C. 9 3 days 5 D. 10

Number syetem tricks by5

Division rule by 5

A last digit of a number must be 0 or 5 then the whole number must be devided

Introduction: What is a Number System?

You probably already know what a number system is - ever hear of binary numbers or hexadecimal numbers? Simply put, a number system is a way to represent numbers. We are used to using the base-10 number system, which is also called decimal. Other common number systems include base-16 (hexadecimal), base-8 (octal), and base-2 (binary).

In this article, I'll explain what these different systems are, how to work with them, and why knowing about them will help you.

Activity

Before we get started, let's try a little activity for fun. There are many different ways to represent a color, but one of the most common is the RGB color model. Using this model, every color is made up of a combination of different amounts of red, green, and blue.

You may be wondering how colors relate to number systems. In short, on a computer, any color is stored as a large number: a combination of red, green, and blue. (We'll go into more detail on this later.) Because it's just a number, it can be represented in multiple ways using different number systems.

Your job is to guess how much red, green, and blue is in the background color of the activity below. The values for red, green, and blue can range from 0 to 255.

Feel free to use the various hints provided to help you out. If you don't understand the numerical hints yet, no problem! You can see what your guess looks like using the View Guess button. Right now, it may seem tricky, but hopefully by the end of the article, it will seem easy.

Division rule by 8

2^3=8

Soif the last three numbers is devided by 8 then the whole number is devisible by 8

Ex:-

2825832

Ans) 832÷8

          =104

So 2825832 is devisible by 8
