Question

Shopkeeper by 50 pens in 200 rupees & sell them at 40 pens of RS 240.Find his gain or loss percent.

Answer 1

Answer: PROFIT%= 50%

Step-by-step explanation:

CP of 50 pens= ₹ 200

CP of 1 pen= ₹ 200/50

                          ₹ 4

now,

SP of 40 pens= ₹240

SP of 1 pen= ₹240/40

                     ₹6

Since, SP>CP, 6>4,

there is profit.

profit= 6-4

           ₹2

Profit%= profit/CP*100

              2/4*100

Profit%= 50%

Hope it might be clearer now:)
