Let the selling price of each mango=Rs.x

Selling price of 125 mangoes=Rs.125x

Profit gained=Rs.5x

CP=SP-Profit

hi

By selling 125 mangoes ,a man gain an amount equal to selling price of 5 mangoes . find the gain per cent

-----------------------------------------------------

let sp of on mango be rs1

then sp of 125mangoes = 125 × 1

                                          = rs 125

now he gains sp of 5 mangoes = 5×1

= rs5

so,

cp = sp - gain

cp = 125-5

cp=120rs

now gain% = gain * 100 / cp

                    = 5 * 100/120

      gain%               =  4.16666............

                gain%                  = 4.167 %
