In a bag there are coins of ₹5, ₹10 and ₹20 denominations. The total number of coins in the bag is 240. If the number of coins of ₹5, ₹10 and ₹20 denominations are in the ratio of 2 : 3 : 5, then what is the total amount of money in the bag?
If the number of coins of ₹5, ₹10 and ₹20 denominations are in the ratio of 2 : 3 : 5
Let's assume the number of coins of ₹5, ₹10 and ₹20 denominations are 2y, 3y and 5y.
The total number of coins in the bag is 240.
2y+3y+5y = 240
10y = 240
y = 24
Total amount of money in the bag = $$₹5 \times 2y+₹10 \times 3y+₹20 \times 5y$$
= $$10y+30y+100y$$
= 140y
Put the value of 'y'.
= $$140\times24$$
= ₹3,360
