PERCENTAGE PROFIT 3

A man got a profit of 7800/= after selling an item. Find the buying price if the percentage profit was 10%.

Solution

%’ge profit = Profit   X  100    where B. P. represents Buying Price.

                         B.P

10% = 7800   X  100   

            B.P.

B.P. x 10% = 780,000   x B.P.  [multiplying by B.P. both sides]

                       B.P.

B.P. x 10 = 780,000   

        

B.P. x 10¹ =   780,000   

  ₁10                   10

B.P. =78,000

                      

Hence Buying Price was 78,000/=
