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

Step-by-step explanation:

let the C.P. of one shirt =rs x

C.P.Of 11 shirt=11x

S.P.of 10 shirts=10x

since S.P.>C.P. hence there will be profit

profit%=sp-cp/cp×100=11x-10x/10x ×100

=x/10 × 100=10%

hence , the profit is of 10%

Answer 2

Step-by-step explanation:

$cp \: of \: 11 \: shirts = sp \: of \: 10shirts \\ let \: cp \: of \:1 \: shirt \: be \: 1 \\ so \: cp \: of \: 11 \: shirts = 11 \\ cp = sp \: so \: \\ sp \: of \: 10 \: shirts = 11 \\ sp \: of \: 1 \: shirt = \frac{11}{10} \\ sp \: of \: 11 \: shirts = \frac{11}{10} \times 11 \\ = \frac{121}{10} \: sp \\ = 11 \: cp$

once u get sp and cp do normal calculations
