Question

3/5 of John’s savings is equal to 2/3 of Mark’s savings. The difference in their savings is equal to 1/5 of Bill’s savings. If John saves $35 more than Bill, how much must Mark give to Bill so that both of them have the same amount of money?

Answer

This is a common ratio question.

LCM

3/5 = 6/10

2/3 = 3/9

     Quantity    
John 10u    
Mark 9u     
Bill  5u    

10u – 5u = 5u

5u = 35

1u = 35 ÷ 5 = 7

9u – 5u = 4u

4u ÷ 2 = 2u

2u = 2 × 7 = $14

3/5 = 6/10
John’s savings : 10 units
2/3 = 6/9
Mark’s savings : 9 units
10 – 9 = 1
1 x 5 = 5
Bill’s savings : 5 units

10 – 5 = 5 units = 35
1 unit = 7
9 + 5 = 14
14/2 = 7

9 – 7 = 2
or
7 – 5 = 2

2 x 7 = 14

Ans : $14.
