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

Solution:

Selling Price of both coolers = Rs. 3990 each

Gain on selling cooler = 5%

Therefore cost price of the cooler = [100/105] × 3990 = Rs. 3800

Loss on selling the other cooler = 5%

Therefore the cost price of the other cooler = [100/95] × 3990 = Rs. 4200

Total Cost Price of both coolers = Rs. 3800 + Rs. 4200 = Rs. 8000

Total Selling Price of both coolers = Rs. 3990 + Rs. 3990 = Rs. 7980

Overall loss on sale of two coolers = Rs. 7980 - Rs. 8000 = Rs. 20

Loss% on the whole transaction = [20/8000] × 100 = 0.25%

✦ Try This: Ashima sold two coolers for Rs 4554 each. On selling one cooler she gained 10% and on selling the other she suffered a loss of 10%.Find her overall gain or loss % in whole transaction.

Selling Price of both coolers = Rs. 4554 each

Gain on selling cooler = 10%

Therefore cost price of the cooler = [100/110] × 4554 = Rs. 4140

Loss on selling the other cooler = 10%

Therefore the cost price of the other cooler = [100/90] × 4554 = Rs. 5060

Total Cost Price of both coolers = Rs. 4140 + Rs. 5060 = Rs. 9200

Total Selling Price of both coolers = Rs. 4554 + Rs. 4554 = Rs. 9108

Overall loss on sale of two coolers = Rs.9108 - Rs. 9200 = Rs. 92

Loss% on the whole transaction = [92/9200] × 100 = 1%
