• Ans: 50
  
  According to problem, Total coins are 150.
  
  Let the total number of 50p coins are x.
  then total number Rs. 1/- and 25p coins are 150-x.
  
  Then (x)(0.5) + (150-X)(1+0.25) = Rs. 150
  
  then x=50.

• 0 as 150 coins of re 1 constitute Rs 150 which is the amount in the bag so no 50 paise coins

• 50x+(150-x)=15000
  on soving we get x=50

• Let x, y and z be the number of Re. 1, 50p and 25p in the bag.
  As per the given condition,
  x+y+z = 150
  And,
  x+0.5y+0.25z = 150
  
  Implies, x+y+z = x+0.5y+0.25z
  Implies, y+z = 0.5y+0.25z
  Implies, 0.5y+0.75z = 0.
  
  Implies y and z = 0 each.
  Hence, x = 150
