Question

A book seller sold a box of 10 pencils for Rs. 80 and incurred a loss. Had he sold it for Rs. 98, his gain would have been twice the loss he incurred earlier. The cost price of the box of pencils is: 

Options

• Rs. 84 

• Rs. 86

• Rs. 88 

• Rs. 90 

Answer 1

Rs. 86

Explanation:

Let the cost price of the pencil box is ₹ x

Then, loss = (x − 80)

Profit = (98 − x) = 2 (x − 80)

3x = 98 + 160

`"x"=258/3`= 86

Hence, the cost price of the pencil box = Rs. 86
