Explanatory Answer

Key Data

  1. The MRP of the product is 55% above its manufacturing cost.
  2. The retailer sells the product after offering a discount of 10% on the MRP.
  3. The retailer makes a 23% profit on his purchase price.

Useful Assumption

In Profit Loss questions where all data is given in percentage terms, assume cost price to be 100.
  Let the manufacturing cost = 100

The MRP of the product is 55% above its manufacturing cost
  The MRP of the product = 100 + 55% of 100 = 155.

The retailer sells the product after offering a discount of 10% on the MRP
  So, the retailer sells the product at 155 – 10% of 155 = 155 – 15.5 = 139.5

The retailer makes a 23% profit on his purchase price
Let the purchase price for the retailer be x.
  So, the retailer sells the product at x + 23% of x = 123% of x.

Step to retailer sells the product @ 139.5 = 123% of x
1.23x = 139.5
(or) x = \\frac {139.5} {1.23}\\)
Therefore, x = 113.4

x is the purchase price for the retailer.
So, x has to be selling price for the manufacturer.
The manufacturer sold the product at 113.4.

Cost to the manufacturer is 100.
So, profit made by the manufacturer is 13.4.
Because we assumed the cost price to be 100, the manufacturer makes a 13.4% profit.

Rounded to the nearest integer, it is 13%

  The correct answer is Choice D.
