A shopkeeper buys some bottles for Rs.900, some lunch boxes for Rs.450 and some calculators for Rs.480. If he sells the bottles at10% loss, Lunch boxes at 40% profit and calculators at 10% loss, find his overall gain or loss?
A. Rs.36 loss
B. Rs.42 profit
C. Rs.30 profit
D. Rs.45 Loss
E. No loss and no gain
Sol:
Total CP of all the products = 900 + 450 + 480 =
1830
Total SP of all the products = (900 * 90/100) +(
450 * 140/100) + (480 * 90/100)
= 810 + 630 + 432
= 1872
Profit = 1872 – 1830 = Rs.42
