Ages — scaling and future ratio (Anil and Purvi): At present Anil is 1.5 times Purvi’s age. Eight years hence, the ratio Anil:Purvi will be 25:18. Find Purvi’s present age.

Introduction / Context:Present multiplicative relation plus a future ratio gives two equations in one unknown (Purvi). Solve directly to find her current age.

Given Data / Assumptions:

• A = 1.5P (present).
• (A + 8) : (P + 8) = 25 : 18.

Concept / Approach:Express Anil in terms of Purvi, substitute into the future ratio, and solve for P.

Step-by-Step Solution:

Verification / Alternative check:

Why Other Options Are Wrong:

• 50, 42, 36 are not Purvi’s present age; they confuse the variables or time shift.

Common Pitfalls:

• Using 1.5P as P/1.5 or swapping numerator/denominator in the ratio.

Final Answer:28 yr
