Question

By selling 125 cassettes, a man gains an amount equal to the selling price of 5 cassette. Find the gain percent

Answer 1

Let the cost of each cassettes be x ,

C.P = 125x

Gain = 5x

S.P - C.P = 5x
S.P = 5x+125x
S.P = 130x

Profit percentage
= (5x/125x) × 100
= 1/25 × 100
= 4%

Answer 2

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 %
