Answer 1

CP=RS.900

SP=RS.972

here,SP>CP

therefore,profit=SP-CP

                        =RS.(972-900)

                        =RS.72

NOW
profit%=P/CP×100%

           =72/900×100%

           =8%

Answer 2

Greetings..!!

Cost Price(C.P) of the radio set = Rs 900

Selling Price(S.P) of the radio = Rs 972

Here , S.P > C.P , so its a gain .

Now, gain = S.P - C.P

⇒972 - 900

⇒ 72

∴ Gain Percent = (Gain/C.P)*100

⇒(72/900)*100

⇒8

Answer : Hence , gain percent is 8% .
