Question

- A trader sells two items at the rate of Rs 400 each. If he gains 15% on one and losses 15% on other, then what is the value (in Rs) of loss ?

Answer 1

let, x and y be the production costs in Rupee.

The item where he gains 15% is sold by 115x/100 INR.

So, 115x/100 = 400
or, 115x = 40000
or, x = 40000/115
or, x = 347.83 INR

The item where he loses 15% is sold by 85y/100 INR.

So, 85y/100 = 400
or, y = 40000/85
or, y = 470.59

Total production cost= 470.59 + 347.83 = 818.42 INR.
Total selling price = 400 + 400 = 800 INR

Loss= 818.42 - 800
= 18.42 INR

Therefore, his loss is 18.42 INR.
