.............................................................................................

Find the selling price of the two pair of jeans:

1 pair of jeans = Rs 990

2 pairs of jeans = 990 x 2 = Rs 1980

.

Find the cost price of the one that he gains 10%:

100 + 10 = 110%

110% = Rs 990

1% = 990 ÷ 110 = Rs 9

100% = 9 x 100 = Rs 900

.

Find the cost price of the one he sold at a loss of 10%:

100 - 10 = 90%

90% = Rs 990

1% = 990 ÷ 90 = Rs 11

100% = 11 x 100 = Rs 1100

.

Find the total cost price:

Total cost price = 900 + 1100 = Rs 2000

.

Find the gain/loss:

Since the total cost price is more than then total selling price

⇒ it is a loss

Loss = 2000 - 1980 = Rs 20

Loss percentage = 20/2000 x 100 = 1%

.

Answer: The transaction has a loss of 1%
