Question

a laptop and Mobile were bought for rs 40000 and 24000 profit 8% on laptop and 12% loss on mobile find gain or loss percentage on whole trasection

Answer 1

40000×8%=3200
24000×12%=2800
then profit,
3200-2800=400
400/64000×100=.625%

Answer 2

CP of Laptop = 40,000

Profit = 8%

SP = 108% of 40,000 = 43,200

CP of Mobile = 24,000

Loss = 8%

SP = 92% of 24,000 = 22,080

Total CP = 40000 + 24000 = 64000

Total SP = 43200 + 22080 = 65280

Since SP > CP , there is a profit on overall transaction.

Profit = 65280 - 64000 = 1280

Profit% = (1280/64000) × 100 = 2

Profit on overall transaction is 2% ............ Answer
