in a class if 5 students are seated in a bench then 2 benches will be vacant.if 4 students are seated in a bench then 10 students will not have benches to sit.then the number of students and benches in the class are

• Let x be the no of benches.
  And y be the no of students.
  So 5(x-2) = y ....(1)
  and 4x = y - 10 ...(2)
  By Solving equations,x = 20 and y = 90

• students=90,benches=20
  
  5(B-2)=S........>1
  4B=S-10..........>2
  
  5B-10=S
  4B+10=S
  SOLVING WE GET B=20 & S=90
  HENCE students=90,benches=20

• let x= no of students and y= no of benches
  so 5(y-2)=x
  4y=x-10
  by solving both the equations we get x=90 and y=20
