Question

sp=rs1250,profit=25%,find cp

Answer 1

Profit % = ( Profit / CP ) * 100

25 % = ( 1250 - CP / CP ) * 100

=> 25 CP = ( 1250 - CP ) * 100

=> 25 CP = 125000 - 100 CP

=> 100 CP + 25 CP = 125000

=> 125 CP = 125000

=> CP = 125000 / 125

=> CP = Rs. 1000.

Hence the Cost Price ( CP ) = Rs. 1000.

Hope my answer helped !
