Question

if the cost price of 8 pens in same as the selling price of 6 Pence then the gain percent is

Answer 1

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% = 48×100% = 50%

Answer 2

Let Selling Price of one Pen be x

Selling Price of 8 Pens = 8x and

Selling Price of 6 Pens = 6x

It is given that Cost Price of 8 Pens = Selling Price of 6 Pens

Cost Price of 8 pens = 6x

But Selling Price of 8 pens = 8x

∵SP > CP, it is a Profit

Profit = SP - CP

= 8x - 6x

Profit = 2x

Profit% = (Profit/CP)×100

(2x/6x)×100

100/3% or

$33 \frac{1}{3}$ %
