A is 40% less than B, and C is 40% of the sum of A and B. The difference between A and B is what percentage of C?
Answer & explanation
Correct answer: option 3
Let the value of B be 100.
Value of A = 100 × \(\frac{60}{100}\) = 60
Value of C = (60 + 100) × \(\frac{40}{100}\) = 64
Required difference = [ \(\frac{100-60}{64}\)] × 100 = 62.5%
