Answer: (1) 1: 3

Explanation:-
The ratio of age of Ram and his mother = 3: 11
Let the age of Ram and his mother = 3 X and 11 X

The difference of their ages is 24 years,
Then, 11 X – 3 X = 24
8 X = 24
X = 24/8
X = 3

Then, the age of Ram = 3 X = 3 x 3 = 9 years and his mother = 11 X = 11 x 3 = 33 years

The age of Ram after three years = 9 + 3 = 12 years
The age of his mother after three mother = 33 + 3 = 36 years

Then, the ratio of their ages after 3 years = 12: 36
= 1: 3

Hence, the answer is (1) 1: 3.
