Question

The selling price of 12 pens is equal to the cost price of 14 pens. Find the gain per cent.​

Answer 1

Answer:

16.67% gain

Step-by-step explanation:

Let the C.P. of 1 pen be Rs.1.

C.P. of 14 pens = Rs.14

S.P. of 12 pens = Rs.14

But, C.P. of 12 pens = Rs.12

Gain = Rs.(14-12) = Rs.2

Gain% = 2/12 × 100 = 16.67%
