Question

If the cost price of 11 shirts is equal to the selling price of 10 shirts, find the percentage profit or loss.

Answer 1

suppose c.p. of 11 shirts =

s.p. of 10 shirts =

s.p. of 10 shirts = 100×11÷ 10

1100÷10= 110

gain = 110-100=10

gain%=10×100÷100

= 10%

Answer 2

Answer:

Step-by-step explanation:

Let the C.P of 1 shirt be RS 1.

.: C.P of 11 shirts = S.P of 10 shirts=

Rs 11.

.: If C.P of 1 shirt is RS 1

.: C.P of 10 shirts=RS 10.

Hence,S.P of 10 shirts=RS 11.

.: Profit=11-10= 1.

.: Profit%=profit/c.p*100

.: ". = 1/10*100

= Rs 10.
