A shopkeeper has $680 in the denominations of $50, $20, $10 and $5 notes. The number of notes of each denomination is equal. What is the total number of notes?

Respuesta :

The total number of notes is 32

The number of notes

Let the number of notes be x

$50 = x

$20 = x

$10 = x

$5 = x

Total number of notes = 4x

Let's find 'x'

50x + 20x + 10x + 5x = 680

85x = 680

x = 680/ 85

x = 8

We know that;

Total number of notes = 4x = 4 × 8 = 32 notes

Thus, the total number of notes is 32
