- A. 138
- B. 138
- C. 138
- D. 138
Answer: Option A
Explanation:
Let, Kalam = k; Shaila = S, Meena = M; Tina = TCoditionally, k - 3 = 2(T - 3) - - - - - - - - (i)
k = M + 30 - - - - - - - - - (ii)
k = S + 47 - - - - - - - - - - - - (iii)
2(S + 4) = T + 4or, 2S + 4 = TFrom (i)
We get k - 3 = 2(2S + 4 - 3)or, k = 4S + 5From (iii)
We get 4S + 5 = S + 47 = > 3S = 42S = 14k = 14 + 47 = 61
M = 61 - 30 = 31
T = 2x14 + 4 = 32
Total = 14 + 31 + 32 + 61 = 138 (Ans.)
