Question

FIND THE formula TO CALCATE THE FOLLOWING:

Find the selling price (s) of an object when a shopkeeper makes a profit of 15% on its cost price (c).


​

Answer 1

Let C.P = 100
Profit%= 15%
Then S.P= CP(100+P%)/100
= 100(100+15)/100
= 100*115/100
= 115₹

Answer 2

Answer:

 CP = ( SP * 100 ) / ( 100 + percentage profit).

CP = ( SP * 100 ) / ( 100 – percentage loss ).

Tips:

Use the above formulas on the bases of percentage profit or loss.
