Ankit sold two jeans for Rs. 990 each, on one he gains 10% and on other he lost 10%. Find his gain or loss percent in the whole transactions.

Answer

Overall CP of one jeans = 990

One jeans is sold at 10% gain. This means if CP is Rs.100,

SP is 110

Therefore, if CP is 990, then,

SP = Rs. 1089

And also, second jeans sold at 10% loss, it means if CP is Rs.100, then SP is Rs.90

Therefore, when CP is 990,

Then,

SP = Rs. 891

We need to find the combined SP and CP to say whether there was an overall profit or loss.

Total CP = 990 + 990 = 1980

Total SP = 1089 + 891 = 1980

Since total SP and CP are same so there is no loss or no profit.

Answer 2

No. of pairs of jeans Ankit had = 2

Cost of each pair is 990 rupees

Now, let's calculate the amount for the first pair.

C.P = Rs.990

Profit = 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.990

Loss = 10%

Hence, loss = Rs.99

So, 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.
