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)?

Shreya's present age = $$56$$ years

Ratio of present ages of Shreya and her husband = $$8:9$$

=> Shreya's husband's present age = $$\frac{9}{8}\times56=63$$ years

Her husband's age 9 years from now = $$63+9=72$$ years

Ratio of her husband's age and her son's age 9 years from now = $$9:4$$

=> Son's age 9 years from now = $$\frac{4}{9}\times72=32$$ years

$$\therefore$$ Son's present age = $$32-9=23$$ years

=> Ans - (A)
