A wallet contains ₹20, ₹10, and ₹5 notes in the ratio 2:3:5. If the total amount is ₹760, find the number of notes of each kind.

1. 12 of ₹20, 18 of ₹10, 30 of ₹5
2. 16 of ₹20, 24 of ₹10, 40 of ₹5
3. 20 of ₹20, 30 of ₹10, 50 of ₹5
4. 14 of ₹20, 21 of ₹10, 35 of ₹5

Correct answer: 16 of ₹20, 24 of ₹10, 40 of ₹5

Solution

Let the numbers of ₹20, ₹10, and ₹5 notes be \(2x, 3x, 5x\). Their total value is \(40x+30x+25x=95x\), and \(95x=760\) gives \(x=8\). Hence the counts are 16, 24, and 40.
