Question

Narendra sells two cookers for ₹2574 each. On one he gains 10% and the other he loses 10%. Find the gain or loss per cent in the whole transaction

Answer 1

Let Cost price of cooker = x
One he gains 10 % => Profit = 10/100 * x = 0.1x

Total amount =1.1x = 2574 => x= Rs. 2340
Profit = Rs. 234

Another he loses 10% => loss = 10/100 *x = 0.1x
Total Amt = 0.9x = 2574 => x= Rs. 2860
Loss = Rs. 286

Total CP of Cookers = Rs 2860 + Rs 2340
= Rs. 5200

Total SP of Cookers = 2 x 2574 = Rs. 5148

Since SP<CP , loss ...
Loss percent = (5200-5148)/5200 x 100 = 1%

There is 1% loss
