In one box, three different types of old coins are in the ratio of 3: 5: 7, the value of old coins is Rs. 1, 5 and 10 rupees respectively. If the total cost of coins placed in the box is Rs 882 So, tell the number of old coins of 10 rupees.
63
Let the numbers of Re 1, Rs 5 and Rs 10 coins be 3k, 5k and 7k.
Total value \(= 3k \times 1 + 5k \times 5 + 7k \times 10 = 3k + 25k + 70k = 98k\).
\(98k = 882 \Rightarrow k = 9\).
Number of Rs 10 coins \(= 7k = 7 \times 9 = 63\).
Hence, there are 63 coins of 10 rupees.
