Question

A wallet contains a total of ₹60 in denominations of ₹5 and ₹10. If the number of ₹10 notes is x and number of ₹5 notes is y, then frame an equation to represent the total amount in the wallet.

• A. 10x + 5y = 60
• B. 10x - 5y = 60
• C. 5x + 10y = 60
• D. 5x - 10y = 60

Answer 1

The correct option is A

10x + 5y = 60

Number of ₹10 notes = x

Number of ₹5 notes = y

Total value of ₹10 notes = 10x

Total value of ₹5 notes = 5y

Therefore the total amount can be represented as 10x + 5y = 60.
