Question

By selling 32 oranges for rs. 30 a man losses 25%. how many oranges should be sold for rs. 24 so at to gain 20% in the transaction?

Answer 1

first find the cost price of oranges .

CP={100/(100-Loss%)}*SP

CP={100/(100-25)}*32*30

CP=1280

NOW FIND THE SP OF ORANGES ON WHICH PROFIT WOULD BE 20% AND THEN DIVIDE IT BY 24.

SP={(100+PROFIT%)/100}*CP

SP={(100+20)/100}*1280

SP=1536

NUMBER OF ORANGES=1536/24=64
