Topic-Linear Equation

A certain number of candidates appeared for examination in which one fifth of the whole + 16 secured first division,one fourth + 15 secure second division and one fourth- 25 secure third division.Of the remaining 60 candidates, find total number of candidates appeared

Answer 1

let total number of candidates be X
so candidates who secured first Division=1/5x+16
second division=1/4x+15
third division=60-1/4x+25
so, X=1/5x+16+1/4x+15+60-1/4x+25
X=1/5x+116
4/5x=116
X=145
