Question

Find the profit or loss per cent, if
C.P. = 30 ; S.P. = 42 ​

Answer 1

Answer:

40%

Step-by-step explanation:

since SP is greater than CP it means it will gain profit

profit%= SP-CP/CP*100

profit%= 42-30/30*100%

profit%= 12/30*100%

profit%= 40%

Answer 2

Answer:

C.P.= 30

S.P.=42

S.P. > C.P.

Gain = S.P. - C.P.

Gain = 42 - 30

Gain = 12

Gain per cent = loss÷C.P. × 100

Gain per cent = 12÷30×100

Gain per cent = 40%
