A bag contains an equal number of 50-paise, 25-paise, 20-paise and 5-paise coins. If the total monetary value of all these coins taken together is ₹55, then how many coins of each type are there?

55

Here,

50p : 25p : 20p : 5p

 1    :    1  :  1   :  1

⇒ (50 + 25 + 20 + 5) = Rs. 55

⇒ 100p = Rs. 1 units = 55

⇒ No. of coins of each type = 1 x 55 = 55.
