A's weight is 25% of that of B and 40% of that of C. What percentage of C's weight is B's weight?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 160%
Both B and C are given in terms of A’s weight, so write each of them as a multiple of A and then compare B with C.
A is 25% of B, so \(B=4A\)
A is 40% of C, so \(\displaystyle C=\frac{100}{40}A=2.5A\)
\(\displaystyle\frac{B}{C}\times100=\frac{4A}{2.5A}\times100=160\%\)
