Question

The original price of an item is discounted by 30%. In order to restore this discounted price to the original price, the discounted price must be increased by x%, where x is closest to

A. 23
B. 30
C. 35
D. 43

Answer 1

we are looking for reciprocal evolution

decrease coefficient = 1-(30/100)= 0.7

reciprocal evolution coefficient: 1/0.7=1.4285...=1.43

% increase to apply to find the original price:

(1.43-1)*100 = 43%
