Question

A shopkeeper buys pens at the rate of Rs 75 per hundred. For how much should he sell each pen so as to make a gain of 15%

Answer 1

15 percent of 75 is 11.25 we have to multiply 75 *11.25=843.75

Answer 2

He should sell each pen of Rs.0.8625 so as to make a gain of 15%

Step-by-step explanation:

Cost price of 100 pens = Rs.75

Cost price of 1 pen=$\frac{75}{100}=0.75$

Gain% = 15%

Gain = $15\% \times 0.75=0.1125$

SP = CP+Gain = 0.75+0.1125=0.8625

So, He should sell each pen of Rs.0.8625 so as to make a gain of 15%
