Mona bought a calculator for rs. 860 and sold it at a gain of 15%. find the selling price of the calculator?

Answer :

sami99
CP(cost price) of the calculator= Rs. 860
by selling it Mona gains= 15%
SP(selling price) when G% and CP is given =
SP= 100+G(%) /100* CP
SP= 100+15 x 860  
          100
SP= Rs.989
Thus Mona sells it at Rs. 989
CP = Rs 860
Profit % = 15 %
SP = 100 + P%  * CP
            100
SP = 100 + 15  * 860
             100
SP = 115 * 860/100
SP = Rs 989
Thus, Mona sold it at Rs 989.
