Rio, Ace and Ray had the same number of notes. Rio and Ace had a mix of $100-notes and $50-notes. Rio had 3 $100-notes while Ace had 11 $100-notes. Ray only had $100-notes.
- Who had the least amount of money?
- How much more did Ace have than Rio?
- Ace used all his $50-notes to buy a wallet. He then had $2700 less than Ray. How many $100-notes did Ray have?
(a)
The three boys had the same number of notes.
$100-notes have a higher denomination than $50-notes.
Since Rio had the least number of $100-notes, he had the least money.
(b)
Number of more $100-notes that Ace had than Rio
= 11 - 3
= 8
Difference in the value of $100-note and $50-note
= 100 - 50
= $50
Amount that Ace had more than Rio
= 8 x 50
= $400
(c)
Value of $100-notes that Ace had left
= 11 x 100
= $1100
Total value that Ray had
= 1100 + 2700
= $3800
Number of $100-notes that Ray had
= 3800 ÷ 100
= 38
Answer(s): (a) Rio; (b) $400; (c) 38
