Correct Answer - Option 3 : 28 years
Let the present age of Anamika be A, Malini be M and that of Srinidhi be S.
The, according to the question:
1) Seven years from now, Anamika will be as old as Malini was 4 years ago.
A + 7 = M - 4
⇒ M = A + 11
S = 2 years
And,
2) Srinidhi was born 2 years ago. The average age of Anamika, Malini and Srinidhi 10 years from now will be 33 years.
\({(A + 10 + M + 10 + S + 10) \over 3} = 33 \)
\(A + M + S + 30 = 33 \times 3\)
A + M + S = 99 - 30
A + M + S = 69
Now, by substituting the above values,
A + (A + 11) + 2 = 69
2A + 13 = 69
A = 56 ÷ 2
A = 28 years
Hence, the present age of Anamika is 28 years is the correct answer.
