Ashima sold two coolers for Rs 3,990 each. On selling one cooler she gained 5% and on selling the the other she suffered a loss of 5%. Find her overall gain or loss % in whole transaction.

Given that, selling price of coolers = Rs.3990 each.On first cooler, gain = 5% and on second cooler, loss = 5%

For first cooler -


∵ Gain = Selling price - cost price




⇒ cost price of first cooler = Rs.3800


For second cooler -


∵ Loss = cost price - Selling price




⇒ cost price of second cooler = Rs.4200


∴ total cost price = Rs.3800 + Rs.4200


= Rs.8000


And total selling price = Rs.3990 × 2


= Rs.7980


⇒ cost price>selling price ⇒ loss


And loss = total cost price - total selling price


= Rs.8000 - Rs.7980


= Rs.20




= 0.25%
