A sum of Rs. 400 is to be used to give four cash prizes to students of a school for their overall performance. If each prize is Rs. 20 less than its preceding prize, find the value of each prize.

• x+(x-20)+(x-40)+(x-60)=400
  x=130
  130,110,90,70

• x + x-20 + x-40 + x-60 =400
  4x-120=400
  4x=520
  x=130
  130,110,90,70

• x + (x+20) + (x+40) + (x+60) = 400
  4x + 120 = 400
  so, x= rs.70
  so prizes are rs.70,rs.90, rs.110, rs.130

• x+x+20+x+40+x+60=400
  so x=95
  so prices r 95, 115, 135, 155
