A, B, C, D went to a hotel and planned to share the bill equally. But afterwards they changed their plan and to pay proportional to consumption A paid 240, B & C paid equally, D paid only half the amount that he should have paid based on the first plan. What is the amount paid by B?

• suppose every person pay Rs x
  x+x+x+x=4x
  240+x+x+x/2=4x
  240+5x/2=4x
  4x-5x/2=240
  3x=480
  x=160
  so d pay Rs 80

• Many solutions are possible.
  
  One possible solution is
  If earlier each was supposed t0 pay Rs 160, then now
  A paid 240
  B paid 160
  C paid 160
  D paid 80 Rs.
  
  Suppose total bill is 4x in starting
  so every one is supposed to pay Rs. x
  A ..B.. C.. D
  x + x + x + x = 4x
  240 + 2y + x/2 = 4x
  7x/2 -2y= 240
  
  one eqn with 2 variables.
  
  so many solutions are satisfying this condition.
