Question

A dozen pencils are bought for rs 6 and each sold for re 0.60.Find the loss or gain percent

Answer 1

Gain percentage is 20%.

• A dozen pencils are bought for Rs. 6.
• 12 pencils are bought for Rs. 6.

Cost price of 12 pencils = Rs. 6

• Now each pencil is sold for Rs. 0.60

Selling price of each pencil = Rs. 0.60

Selling price of 12 pencils = 12 × Rs. 0.60

Selling price of 12 pencils = Rs. 7.20

• Now we have to calculate the gain or loss percentage,
• As the selling price is greater than the cost price , it is a gain.
• Gain percentage = $\frac{Gain}{Cost \ price}$ × 100

Gain = Selling price - Cost price

Gain = 7.2 - 6 = Rs. 1.2

• Gain percentage = $\frac{1.2}{6}$ × 100

Gain percentage = 0.2 × 100

Gain percentage = 20%.
