In a bag there are coins of ₹2, ₹5 and ₹10 denominations. The total number of coins in the bag is 300. If the number of coins of ₹2, ₹5 and ₹10 denominations are in the ratio of 1 : 2 : 3, then what is the total amount of money in the bag?
Answer & explanation
Correct answer: option 1
Rs.2 : Rs.5 : Rs.10
1 : 2 : 3
⇒ (1 + 2 + 3)units = 300
⇒ 6 units = 300
⇒ 1 unit = 50
⇒ 1 x 50 x Rs.2 + 2 x 100 x Rs.5 + 3 x 150 x Rs.10
⇒ 100 + 500 + 1500 = Rs. 2100.
