Value of x = 100 , When the price of an item was reduced by 20%, then its sale increased by x%.
Step-by-step explanation:
Let say item price = P
Number of item sold = S
Revenue = P * S
price of an item was reduced by 20%
Hence reduced price = P - (20/100)P = 0.8P
there is an increase of 60% in the receipt of the revenue
=> increased revenue = PS + (60/100)PS = 1.6PS
Number of item sold = 1.6PS/0.8P = 2S
sale increased by x%.
=> S + (x/100)S = 2S
=> x/100 = 1
=> x = 100
Value of x = 100
