300 coins consists of 1 rupee, 50 paise and 25 paise coins, their values being in the ratio of 10 : 4 : 3. Find the number of coins of each type.

100, 80, 120

80, 90, 100

100, 100, 80

60, 80, 100

Value of rupee coins = 10 i.e. 10 coins.

Value of 50 p coins = 4 i.e. 8 coins.

Value of 25 p coins = Rs. 3 i.e. 12 coins.

∴ Ratio of coins = 10 : 8 : 12 ⇒ 5 : 4 : 6.

∴ Number of rupee coins = 5/15 × 300 = 100.

Number of 50 P coins = 4/15 × 300 = 80

and Number of 25 P coins = 6/15 × 300 = 120

Hence, option 1 is the correct answer.
