Q. If 80% of A = 50% of B and B = x% of A, then the value of x is :
Answer: 160
Notes: According to the question, $latex A\times \frac{80}{100} = B\times \frac{50}{100}&s=1$ $latex \therefore B = \frac{A\times 80}{50} = 1.6A&s=1$ $latex \therefore B = 160\% of A$ $latex \therefore x = 160$ Hence option [C] is the correct answer.
