• let, white=x
  then brown=18-x
  let the cost of a brown sharpener is y
  then a/q, x(y+1)+(18-x)y=100
  or x + 18y=100
  x

• 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
