The profit on the sale of a product is 25%.What will be the loss per cent, if the values of cost price and selling price are interchanged?

Solution

let CP=100. PROFIT=25% SO SP=125.

now interchange CP and SP.

CP=125 SP =100

LOSS=25.

LOSS% = 25/125*100 = 20%

SHORTCUT METHOD.

25%=1/4 so CP= 4 SP= 5

INTERCHANGE

CP=5 SP=4 so loss =1/5=20%
