The ratio of the present ages of Reena and her husband is 4 : 5. 8 years from now, ages of her husband and her son will be in the ratio 24 : 9. If the present age of Reena is 32 years, then what will be her son’s present age (in years)?

Reena's present age = $$32$$ years

Ratio of present ages of Reena and her husband = $$4:5$$

=> Reena's husband's present age = $$\frac{5}{4}\times32=40$$ years

Her husband's age 8 years from now = $$40+8=48$$ years

Ratio of her husband's age and her son's age 8 years from now = $$24:9$$

=> Son's age 8 years from now = $$\frac{9}{24}\times48=18$$ years

$$\therefore$$ Son's present age = $$18-8=10$$ years

=> Ans - (C)
