Question

A manufacturer sells an article which costs him Rs5000 at 20% profit the purchaser sells the article at 25% gain find final sale price of the article

Answer 1

cost price of manufacturer = 5000
profit = 20%........so
selling price =( 100+g% )*cost price /100
=> (100+20)*5000/100 = 6000

the selling price of the manufacturer is the cost price of the purchaser . so
cost price of the purchaser = 6000
he sells the article at 25% gain . then ,
selling price of the purchaser =( 100+g% )*cost price /100
=> (100+25)*6000/100 = 7250.
so final sale price of the article is Rs.7250

hope this helps you
