Answer 1

Answer:

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

Answer 2

Given :-

SP of each jeans = 990

Gain on first jeans = 10%

Loss on second jeans = 10%

To Find :-

Loss %

Solution :-

We know that

▪ IN FIRST JEANS

CP = 100 × SP/100 + P%

CP = 100 × 990/100 + 10

CP = 100 × 990/110

CP = 100 × 9/1

CP = Rs. 900

▪ IN SECOND JEANS

CP = 100 × SP/100 - L%

CP = 100 × 990/100 - 10

CP = 100 × 990/90

CP = 100 × 11

CP = 1100

▪ Total CP

Total CP = CP of first jeans + CP of second jeans

Total CP = 900 + 1100

Total CP = 2000

Now

▪ Total SP

Total CP = SP of first jeans + SP of second jeans

Total CP = 990 + 990

Total CP = 1980

Now,

Loss% = Loss/CP × 100

Loss % = CP - SP/CP × 100

Loss % = 2000 - 1980/2000 × 100

Loss % = 20/2000 × 100

Loss % = 2/2

Loss % = 1 %
