If 20% of A = 50% of B, Then what per cent of A is B ?
If 20% of A = 50% of B, Then what per cent of A is B ?
[A]15%
[B]25%
[C]30%
[D]40%
40%
20% of A = 50% of B
$latex => 2A = 5B$
$latex => A = \frac{5B}{2}&s=1$
Let B is x% of A.
$latex \therefore \frac{5B}{2}\times \frac{x}{100} = B&s=1$
$latex => x = \frac{200}{5} = 40\%&s=1$
Hence option [D] is the correct answer.
