Explanation:

- Let's define the present ages:

- Let Anamika's current age be A years.

- Malini's current age be M years.

- Equation 1: Seven years from now, Anamika's age will be A + 7.

- Malini was M - 4 years old four years ago.

- Therefore, A + 7 = M - 4.

- Equation 2: Srinidhi was born 2 years ago, so presently Srinidhi is 2 years old.

- In 10 years, Anamika will be A + 10, Malini will be M + 10, and Srinidhi will be 12.

- The average age of Anamika, Malini, and Srinidhi will be 33 years.

- [(A + 10) + (M + 10) + 12] / 3 = 33.

- Simplifying gives A + M + 32 = 99.

- A + M = 67.

- Solving Equations 1 and 2:

- From Equation 1: M = A + 11.

- Substitute in Equation 2: A + A + 11 = 67.

- 2A + 11 = 67.

- 2A = 56.

- A = 28.

- Therefore, Anamika's current age is 28 years.

- Correct Answer: Option 4 - 28 years.
