Question

By selling a table for Rs. 3168,Rashjd loses 12%. Find it's cost price. What percent would he gain or lose by selling the table for Rs. 3870​

Answer 1

Step-by-step explanation:

let the cost price be cp

then,

sp=cp-(cp*12/100)

3168=cp-3cp/25

3168=22cp/25

cp=3168*25/22

cp=3600

so cost price is 3600

if he sell it for 3870 then,

profit=3870-3600

profit=270

profit%=270*100/3600

profit%=270/36

=7.5%

so profit percent is 7.5%
