Total Pairs of Jeans Ankit had = 2
Cost of each pair = Rs. 990

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, 
Hence , no profit no loss
