# If 80% of A = 50% of B and B = x% of A, then the value of x is :

If 80% of A = 50% of B and B = x% of A, then the value of x is :
[A]150
[B]300
[C]160
[D]400

160
According to the question,
$A\times \frac{80}{100} = B\times \frac{50}{100}$
$\therefore B = \frac{A\times 80}{50} = 1.6A$
$\therefore B = 160\% of A$
$\therefore x = 160$
Hence option [C] is the correct answer.
