Question

FIND GAIN OR LOSS PERCENTAGE :-

1) C.P =90 , S.P =100
​

Answer 1

since C .P is smaller than S. P,

thus,

profit= 100- 90= 10

...

thus, p%= 10/90×100= 100/9= 11 1/9%

Answer 2

Cp = 90, sp=100

profit = sp-cp

= 100- 90

= 10

profit % = profit÷ cp ×100

10÷ 90 ×100

= 100÷9

= 11.11 (answer)
