Peter bought an item from a manufacturer for $C with the intention of selling the item for $S in a nearby market. However, he decided to offer a discount of 20% on $S and he sold the item at this discounted price for a profit of 10%. If $S is 65% greater than the manufacturer's cost of the item, then what is the profit percentage earned by the manufacturer?
A)10.0%
B)12.8%
C)15.0%
D)16.6%
E)20.0%
For the manufacturer, C is the selling price.
For Peter, C is the Cost price and S is the Marked Price
On this Marked Price he gives a discount of 20%. Therefore the SP = 80% of MP = 0.8S ... (!)
Now he makes a 10% profit on C, therefore SP = 1.1C ... (2)
Equating 1 and 2, we get 1.1C = 0.8S or C = \(\frac{8}{11}S\) (This is the manufacturers SP)
We are also given that S is 65% more than the manufacturers CP.
Let the manufacturers CP = M
Then S = 1.65M
or M = \(\frac{S}{1.65} = \frac{100}{165}S = \frac{20}{33}S\)
Profit % = \(\frac{SP - CP}{CP} * 100 = \frac{\frac{8}{11} - \frac{20}{33}}{\frac{20}{33}} * 100= \frac{\frac{24 - 20}{33}}{\frac{20}{33}} * 100 = \frac{4}{20} * 100 = 20\)%
