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?

Let's assume the number of each type of coin in the bag is 'y'.

Here coins are in 'paise'. But the total monetary value is in rupee. So we will convert ₹55 into paise.

1 rupee = 100 paise

55 rupee = 5500 paise

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.

50y+25y+20y+5y = 5500

100y = 5500

y = 55

So 55 coins of each type are there in the bag.
