A bag contains ₹5, ₹2, and ₹1 coins in the ratio 2: 3: 4, if the total amount of money in the bag is ₹200, find the number of coins of each kind.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 20 coins of ₹5, 30 coins of ₹2, and 40 coins of ₹1.
Let the number of ₹5 coins = 2x, ₹2 coins = 3x, ₹1 coins = 4x
Total value = 5 × 2x + 2 × 3x + 1 × 4x = 10x + 6x + 4x = 20x
20x = 200
⇒ x = 10
₹5 coins = 2 × 10 = 20
₹2 coins = 3 × 10 = 30
₹1 coins = 4 × 10 = 40
