Two toy stores, A and B, sell Hot-Wheels. The regular price at store A is 80% of the manufacturer’s suggested retail price. Store B normally does not offer any discount on the manufacturer’s suggested retail price. During Christmas, both stores offer special discounts. What is the difference between the prices of the toys of the two stores?
(1) Store A offers a special discount of 20% on its regular price and finally sells at $64.
(2) Store B offers 40% discount on its regular price.
Let the manufacturer's suggested retail price be "x"
So store A's regular price = 80%*x = 0.8x
Store B's regular Price = x (as it does not offer any discount)
We need to find: Difference between discounted price of A & B. For that we need to know price of A & B and the discount they are offering
Statement 1: implies that Store A's discounted price = 0.8x*(100%-20%) = 64
or 0.8x*0.8 = 64 -----------(1)
but this statement does not provide any information regarding B's price. Hence Insufficient]
Statement 2: implies that Store B's discounted price = (100%-40%)*x = 0.6x ----------------(2)
but this statement provides no information regarding store A's discounted price. Hence Insufficient
Combining 1 & 2
from equation 1 value of x = 100
So discounted value of store B = 0.6*100 = 60
Therefore difference between store A's discounted price and store B's discounted price = 64-60 = 4
Hence Sufficient
