The ratio of the ages of Meena and Meera is 4 : 3. The sum of their ages is 28 years. The ratio of their ages after 8 years will be

A. 4 : 3
C. 7 : 4
B. 12 : 11
D. 6 : 5
Answer : D

Explanation :

Let meena’s age = 4x and Meera’s age = 3x
Then 4x + 3x = 28
              x = 4
Meena's age = 16 years
and Meera's age = 12 years
Ratio of their ages after 8 years = (16 + 8) : (12 + 8)
                                                = 24 : 20
                                                = 6 : 5
