A bag contains ₹10, ₹5, and ₹2 coins in the ratio 1 : 2 : 3. If the total amount of money in the bag is ₹390, find the number of coins of each kind.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 15 coins of ₹10, 30 of ₹5, and 45 of ₹2.
Ratio of coins = 1x : 2x ; 3x
Total value = 10x + 5(2x) + 2(3x) = 10x + 10x + 6x = 26x
⇒ 26x = 390
⇒ x = 15
Coins:
₹10 coins = 15
₹5 coins = 30
₹2 coins = 45
