Jack buys 18 sharpeners (white and brown) for rs. 100. If he pays 1 rupee more for each white than brown sharpeners. How many of white and how many brown sharpeners did he buy?
","rationale_html":"Total cost=100
number of sharp=18
cost of white=cost of brown+1
100/18=5.5...-(1)
also 100%18=10...-(2)
as cost of white is 1 more than that of brown
from 1 int. value will be 5
now remainder is 10 so 10 sharp. will be of cost (5+1)
=> 10*(5+1)+8*5
=>10*6+8*5
=60+40
100
white=10
brown=8
