A manufacturer makes a profit of 15% by selling a colour TV for rs. 6900.If the cost of manufacturing increases by 30% and the price paid by the retailer is increased by 20%, find the percentage of profit made by the manufacturer.

Read Solution (Total 1)

Profit=15% SP=6900
so CP=6900*(100/115)=6000

manufacture increased 30% on CP
c.p=6000+(6000*30%)=7800

retailer increased 20% on selling price
SP=6900+(6900*20%)=8280

profit=SP-CP
Profit=8280-7800=480

Profit%=(480/7800)*100=6.15 %
