A man purchased a cell phone for ₹2,000. By paying 200 more, he replaces its body Case). If he sells the cell phone for 2,500, find his profit or loss per cent.(7th class math)

solution:Given Cell phone Rs. = 2000

Pay more(he replaces its body case) Rs. = 200

Sell the cell phone Rs. = 2500

According to question,

Actual cost price(C P) of cell phone = 2000 + 200

                                                          = 2200 Rs.

S P > C P, then there is a gain or profit.

then,Profit = S P (sell price) - C P ( cost Price)

                  = 2500 - 2200

                  = 300 Rs.

Profit % = Profit/C P X 100

              = 300/2200 X 100

              = 150/11

              = 13.63 %

Therefore profit is 13.63%.
