The average present age of Anusha, Nila and Diya is 36 years. If the ratio of the ages of Nila and Diya after 4 years is 10:13 and Anusha is 24 years younger than Diya, then find the present age of Nila?
A. 26 years
B. 36 years
C. 46 years
D. 56 years
E. None of these
Sol:
Anusha +Nila + Diya = 36 * 3 = 108
Nila + 4 = 10x
Diya + 4 = 13x
Anusha = 13x – 4 – 24
10x – 4 + 13x – 4 + 13x – 28 = 108
36x = 144
x = 4
Present age of Nila = 40 – 4 = 36 years
