Rahul has a box which contains 25 paise, 50 paise and Rs. 1 coins. If the ratio of number of coins of 25 paise and 50 paise is 4:5 respectively, the number of Rs. 1 coins is 60 and he has Rs. 95 in the box, then the probability of selecting a 50 paise coin is?

Answer 2

Answer:

Given:

Total amount = Rs 1120

Ratio of coins of Rs 1, 50 paisa, and 25 paisa = 1 ∶ 1/2 ∶ 1/3

Formula Used:

Value of coins = Number of coins × per coin value

Calculation:

We know that

Rs 1 = 100 paisa

Ratio of value per coin = 100 ∶ 50 ∶ 25

⇒ 4 ∶ 2 ∶ 1

Ratio of number of coins = 1 ∶ 1/2 ∶ 1/3

⇒ 6 ∶ 3 ∶ 2

Total value of coins = 24 ∶ 6 ∶ 2

⇒ 12 ∶ 3 ∶ 1 = 16 units

⇒ 16 units = 1120

⇒ 1 units = 70

Value of 25 paisa coins = 1 units

⇒ 1 × 70

⇒ Rs. 70

∴ The total number of 25 paisa coins is Rs. 70.
