Question

if x% of y is the same as 4/5 of 80 , the value of xy is ​

Answer 1

Answer:

Given

$x \% of y = \frac{4}{5} \: of \: 80 \\ \therefore \frac{x}{100} \times y = \frac{4}{5} \times 80 \\ \implies \frac{xy}{100} = 4 \times 16 \\ \implies \frac{xy}{100} = 64 \\ \implies xy = 64 \times 100 \\ \implies xy = 6400$
