Question

If a% of x is equal to b% of y, then c% of y is what % of x?

• A. c%
• B. ac/b%
• C. bc/a%
• D. abc%

Answer 1

The Correct Option is B

Given : a% of x is equal to b% of y
\(\rightarrow ax=by\)
\(\rightarrow y=\frac{ax}{b}\)
Multiplying both sides with \(\frac{c}{100}\)
\(\rightarrow \frac{c}{100}\times y =(\frac{c}{100})\times(\frac{ax}{b})\)
\(\rightarrow c\%\) of \(y \) is \((\frac{ac}{b})\%\) of \(x\)
The correct answer is (B) : ac/b%
