Let’s see some problems on Ages

Questions 1. A mother is twice as old as her son. If 20 years ago, the age of the mother was 10 times the age of the son, what is the present age of the mother?

Answer.  Let the age of son = x
Therefore, mother’s age = 2x
20 Years ago mother’s age = 2x – 20
20 Years ago son’s age = x – 20
According to Question
2x – 20 = 10 ( x – 20 )
2x – 20 = 10x – 200
8x = 180
x = 180/8 = 22.5
So, the age of mother = 2x = 2(22.5) = 45 years

Question 2. The ratio of the ages of Neeraj and Divya is 9 : 10 respectively. Ten years ago, the ratio of their ages was 4 : 5 respectively. What is the present age of Divya ?

Answer.  Let Neeraj’s age = 9x and Divya’s age = 10x
10 years age, Neeraj’s age = 9x – 10, Divya’s age = 10x – 10

Divya’s present age = 10x = 10.2 = 20 years

Question 3. Ram’s age after 6 years will be three–sevenths of her father’s age. 10 years ago, the ratio of their ages was 1 : 5. What is Ram’s father’s age at present?

Answer. Let’s Ram’s age 10 years ago is x
Ram’s father age 10 years ago = 5x
Ram’s age after 6 years = x + 10 + 6 = x + 16
Ram’s father age after 6 years = 5x + 10 + 6 = 5x + 16

According to Questions

Ram’s father present age = 5x + 10 = 5×8 + 10 = 50 Years
