Q.1) There are 40 coins in a bag, consisting of Rs. 5 and Rs. 2 coins. If the total amount is

Rs. 140, how

many Rs. 2 and Rs. 5 coins are there in the bag?

• Rs5 *20=100
  Rs2 *20=40
  so 40 coins make 140rs.in this pattern.

• Assume x= 2 Rs coin and y= 5 Rs coin
  From the given information x+y=40 -----eqn1
  and 2x+5y=140-------eqn2
  
  solve eqn 1 and 2 y=20 and x=20
  that means 20 five rupees coins and 20 two rupees coins
