Question

The ratio of the present ages of Shreya and her husband is 8 : 9. 9 years from now, ages of her husband and her son will be in the ratio of 9 : 4. If the present age of Shreya is 56 years, then what will be her son’s present age (in years)?

A) 23 B) 24 C) 19 D) 25

Answer 1

Answer:

Let the present ages of Shreya & her husband be 8a and 9a.

In questionx, given, age of Shreya is 56 year,

So, 8a = 56

= > a = 56/8 = 7

So,

present age of her husband = 9a = 9(7) = 63 years

After 9 years, age of her husband = 63 + 9 = 72 year.

According to question, ratio of ages of husband and her son will be 9:4.

Let their ages will be 9x and 4x.

From above, we can say,

9x = 72 So, x = 72/9 = 8

Hence, after 9 years, age of son = 4x = 4(8) = 32 years.

Hence, present age of son = 32 - 9 = 23 year.
