Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1. i.e. 15 : 14
When son was born
Ratio of ages of father & mother = 11 : 10
Present age of son = x
Son will be twice of age in x years
ATQ,
19 – 11 = 2x = 18 – 10
x = 4
Present age of father = 11 + 4 = 15
Present age of mother = 10 + 4 = 14
Ratio = 15 : 14
