Question

Ankit sold two jeans for rs 990 each on one he gained 10% and on the other he lost 10% find his gain or loss per cent in the whole transaction

Answer 1

Total Pairs of Jeans Ankit had = 2Cost of each pair = Rs. 990
Now, let's calculate the amount for the first pair.
C.P = Rs.990Profit = 10% 
Hence profit = Rs.99 So, the final price will be Rs.990 + 99 = 1089
Now, calculation for the 2nd pair of jeans
C.P = Rs.990Loss = 10%
Hence, loss = Rs.99So, the final price will be Rs.990 - 99 = 891
Now, verify profit or loss
Price of 1st pair + Price of 2nd pair = 1089 + 891 = 1,980 Original price of 1st pair + Original price of 2nd pair = 990 + 990 = 1,980
S.P = C.P, Hence , no profit no loss
