Aarushi Sood  (8 years ago)

let no of white sharpeners be x
" '' brown "" be 18-x

then , let cost of brown sharpener be y
"" "" white "" will be y+1 (as per ques)
x(y+1)+(18-x)y=100
=18y+x=100
putting 5 in place of y (hit n trial assumption as 18*5=90)
then x will be 10
hence , brown sharpener cost 5 Rs and white cost 6 Rs
