Question

If the cost price of 10 pens is equal to the selling price of 8 pens, find the gain or loss per cent. ???​

Answer 1

Step-by-step explanation:

Cp of 1 pen = 1

Cp of 8 pens = 8

Cp is less than selling price

Profit = Sp - Cp

Profit = 2

Profit% = profit/Cp × 100

Profit% = 2/8 × 100

= 100/4

= 25%

Answer 2

Answer:

Cost price of Pen is 10.

selling price of Pen is 8.

C.P is more than S.P.

So,

C.P. - S.P.

10-8=2

Profit%=2/8×100

Profit%=2×12.5

Profit%= 25
