A bag contains 1 rupee, 50 paisa and 25 paisa coins in the ratio 2 : 3 : 4. If the total value of the coins in the bag is Rs. 45, then find the number of 50 paisa coins.
Answer & explanation

1Rs. : 50p : 25p
No. of coins ⇒ 2 : 3 : 4
Value of coins ⇒ 2 : 1.5 : 1 ⇒ 4.5 (total)

⇒ 4.5 R = Rs.45
⇒ 1R = 10
⇒ No. of 50p coins = 3R = 3 × 10 = 30
