Question

If the buying price of an item is 10
and the selling price is * 12, then what
is the percentage of profit ?
(1) 10 %
(2) 20 %
(3) 2%
(4) 40 %​

Answer 1

Here, CP = 10, SP = 12

Profit = SP - CP

         = 12 - 10

         = 2

Now, Profit % = $\frac{Profit}{CP}$  x 100

                       = $\frac{2}{10}$  x 100

                       = 20%

Therefore, (2) 20% is the correct answer.

Answer 2

Answer:

CP of 2 items=10

sp of 2 items=12

profit=sp-cp

=12-10= 2

profit%=profit×100÷cp

=2×100÷10

= 20%
