Question

a) A purchased a pen at Rupees 15 and sold it to
B at 20% profit. If B sells the pen at rupees 17 then what will be his profit or loss?​

Answer 1

B purchase pen at rupees 18 and sales it in 17 rupees so he gets 5.55 percent loss

Answer 2

Answer:

C.P = 15

Profit% = 20

                                  C.P                               S.P

                                   100                              120(with profit)

                                    15                                   x

unitary method:

100x = 15x120

x = 15 x 120

       100

            x = Rs. 18

therefore, C.P of B = 18

S.P = 17

Loss = C.P - S.P

= Rs. 1

Loss percent = Loss/C.P x 100

= 1/18 x 100

= 5.55% loss

Hope you understood (:
