Question

Gunjan sells two watches for Rs. 2400 each, gaining 20% on one and losing 20% on the other. Find grain or loss percent on the whole transaction​

Answer 1

Answer:

The answer would be 4% loss

Step-by-step explanation:The step by step explanation is (120%)*(watch1 S.P.) = 2400r,  (80%)*(watch2 S.P.) = 2400r

watch 1 C.P. = 2000r

watch 2 C.P. = 3000r

Total cost = 5000r

Total selling price = 4800r

Loss = S.P. - C.P. => Loss = 200r

Loss% = (Loss/Cost)*100 => (200/5000)*100

which would mean 4%

!!!!!!!The shortcut is that there is always loss in such situation and the loss% = [(gain or loss % in question)/(10)]^2!!!!!!!!!
