11) The sum of the present age of mother and her son is 60 years. Six years ago, the age of the mother was five times the age of her son. What will be the age of her son after 6 years?

  1. 23 years
  2. 22 years
  3. 20 years
  4. 21 years

Answer: C

Explanation:
Let the present age of the son =x
Then, the present age of the mother =(60-x)
As per question:
Six years ago mother's age was 5 times the age of her son:
So, (60-x) -6=5(x-6)
54 - x = 5x -30
84=6x
x=84/6
x=14 Years
Age of son after 6 years
=x+6
=14+6
=20 Years

  2. 17 years
  3. 16 years
  4. 15 years

Answer: C

Explanation:
The ratio of the ages of Preeti and Ruchi six years ago =6:5
According to Question:
six years ago the age of Preeti=6x
Six years ago age of Ruchi=5x
after 4years, the ratio of their ages =11:10
(6x+10):(5x+10)=11:10
10(6x+10) =11(5x+10)
60x + 100 = 55x + 110
5x=10
x=10/5=2
Ruchi's present age
=(5x+6)=5×2+6=16 years
