Let the present age of Sateesh = x

Let the present age of Murali’s age be = y

10 years ago:

(y – 10) = 3 (x – 10)

y = 3(x – 10) + 10

10 years hence:

(y + 10) = 2 (x + 10)

(3(x – 10) + 10 + 10) = 2 (x + 10)

3x – 30 + 20 = 2x + 20

3x – 2x = 30 – 20 + 20

x = 30

So, y = 3(x – 10) + 10

y = 3(30 - 10) + 10

y = 60 + 10 = 70

The ratio of Murali’s age to Sateesh’s age = 70 : 30 = 7 : 3

Hence, 7 : 3 is the correct answer.
