Question

A shopkeeper bought 11 pencils for 10 and sold at 10 for 11 find his gain or loss percent

Answer 1

Answer:-

21% Profit

• Given:-

CP of 11 pencils = Rs. 10

SP of 10 pencils = Rs. 11

• To Find:-

Gain or loss percentage

• Solution:-

Cost price of 11 pencils is Rs. 10 and Selling price of 10 pencils is Rs. 11.

Hence,

Multiplying CP by 10 and SP by 11:-

Now,

CP of (11×10) pencils = 10× 10

CP = 100

SP of (10×11) pencils = 11 × 11

SP = 121

here,

SP > CP

Hence,

Profit = SP - CP

Profit = 121 - 100

Profit = Rs. 21

Profit percentage:-

Profit/C.P × 100

→ 21/100 × 100

21% Profit
