The ratio of the ages of Maala and Kala is 4 : 3. The total of their ages is 2.8 decades. The proportion of their ages after 0.8 decades will be [1 Decade = 10 years]  Pick
A) 4:3	B) 12:11	C) 7:4	D) 6:5	E) 6:7
Explanation:   Let, Maala’s age = 4A and Kala’s age = 3A   Then 4A + 3A = 28   A = 4   Maala’s age = 16 years   and Kala’s age = 12 years   Proportion of their ages after 8 is = (16 + 8) : (12 + 8)   = 24 : 20   = 6 : 5 .. Answer: 6:5
