100

The cost price C is given by the formula C= (100s)/(100+g) , where S=selling price and g=gain in %. Make S the subject of the formula . Find S, if C=rs800 and g=20. The following steps are involved in solving the above problem. Arrange them in sequential order. (A) rArr100S=C(100+g) (B) S=((100+g)C)/(100) (C) Given C=(100S)/(100+g) (D) therefore S=((100+20)xx800)/(100)=rs960
