Question

A dealer increased the price of an item by 20%, and then increased the price of the same item by 30%. If x is the original price, what is the price after the two increases?

Options

A) 1.5 x

B) 1.56 x

C) x + 0.5

D) x + 0.56

E) x + 6

The correct answer is B.

Explanation:

1st increase = 0.2 of x = 0.2x
Total = x + 0.2x = 1.2x
2nd increase = 0.3 of 1.2x = 0.36x
Total price after the two increases = 1.2x + 0.36x
= 1.56x
