Correct Answer - Option 3 : 27
The ratio of the present ages of S and T is 7 : 9.
Let the common multiple be x.
So, the present age of S = 7x and the present age of T = 9x.
The sum of the present age of S and T is 48 years.
According to question:
7x + 9x = 48
16x = 48
x = 3
Age of T = 9x
= 9 × 3 = 27 years
Hence, the age of T is 27 years.
