Question

A man bought a certain mangoes at 20per rupee and equal number of mangoes at 30 per rupee. He mixed them and sold them at 25 per rupee find loss or gain percentage

Answer 1

let d no.of mangoes be x
price of mangoes of 20 per rupee = x×20= 20x
price of mangoes of 30 per rupee = x×30= 30x
total no.of mangoes = x+x= 2x
total price of 2x mangoes = 20x+30x= 50x

his selling price = 25 per rupee
total selling price = 2x × 25= 50x

cost price of total mangoes = 50x
selling price of total mangoes = 50x

thus he had no profit and no gain
