Let the unknown number be N. If 25% of N is 60, then 0.25N = 60. Solving this equation gives N = 60 ÷ 0.25 = 240. To find 40% of this number, we compute 0.40 × 240, which equals 96. Thus, 40% of the number is 96.
Option A:
Option A, 80, corresponds to one third of 240, not 40%, and would arise from mixing up the percentage multipliers. It does not follow from the given condition.
Option B:
Option B, 90, is 37.5% of 240 and again has no direct link to the required 40% rate. It reflects an incorrect multiplication step.
Option C:
Option C is obtained by first recovering the full value of the number from the 25% information and then correctly applying the 40% factor to it. The arithmetic is consistent at each stage and produces 96.
Option D:
Option D, 100, is slightly higher than the correct value and might come from rounding or a mistaken assumption that 40% is close to half, but it is not the exact result.
