Q:

If the cost price of 12 pens is equal to the selling price of 8 pens, the gain percent is ?

A) 12%	B) 30%
C) 50%	D) 60%

Answer & Explanation Answer: C) 50%

Explanation:

Friends, we know we will need gain amount to get gain percent, right. So lets get gain first.

Let the cost price of 1 pen is Re 1

Cost of 8 pens = Rs 8

Selling price of 8 pens = 12

Gain = 12 - 8 = 4

Gain% = $(\frac{g a i n}{\cos t} \times 100)$ % = $(\frac{4}{8} \times 100)$ % = 50%
