18 sharpner cost =100 rs
1 sharpener cost= 100/18=5.55rs
As the cost of white sharpner is one rupe more than brown sharpner then
5.55+1=6.5rs cost of white sharpner
1 sharpener cost= 100/18=5.55rs
As the cost of white sharpner is one rupe more than brown sharpner then
5.55+1=6.5rs cost of white sharpner
