Solution : Let the number of each coin be $x$ The total monetary value of all these coins taken together is INR 55 = 55 x 100 = 5500 paise The bag contains an equal number of 50 paise, 25 paise, 20 paise, and 5 paise coins The Total monetary value of the coin will be = $50\times x+25\times x+5\times x = 100x$ But the monetary value of coins is 5500 paise ⇒ $100\times x = 5500$ ⇒ $x$ = 55 coins $\therefore$ The bag contains 55 coins of each type. Hence, the correct answer is 55.
