Question

Answer 1

Answer:

50%

Step-by-step 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% = (gaincost×100)gaincost×100%  = (48×100)48×100% = 50%
