Question 82

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 ?

Solution

Selling price of each item = Rs. 400

Profit % on 1st item = 15%

=> Cost price of 1st item = $$400\times\frac{100}{(100+15)}=Rs.$$ $$347.82$$

Similarly cost price of 2nd item = $$400\times\frac{100}{(100-15)}=Rs.$$ $$470.58$$

=> Total cost price = Rs. (347.82+470.58) = Rs. 818.4

and total selling price = Rs. (400+400) = Rs. 800

$$\therefore$$ Loss = CP - SP

= Rs. (818.4 - 800) = Rs. 18.4

=> Ans - (A)
