1. Of the three men, who had the least money? 
2. What was the difference in the total value of Ace and Jim's notes? 
3. Jim used all his $100-notes to buy a present. Ray then had $2620 more than Jim. How many $100-notes did Ray have?

(a)
The three men had the same number of notes.
$20-notes have a lower denomination than $100-notes.

Jim had more $20-notes than Ace while Ray had only the $100-notes.  

Since Jim had the most number of $20-notes, he had the least money.

(b)
Difference in the number of notes of different values
= 14 - 5
= 9

Difference in the value of $100-note and $20-note
= 100 - 20
= $80

Difference in the total value of Ace's and Jim's notes
= 9 x 80
= $720

(c)
Value of $20-notes that Jim had left
= 14 x 20
= $280

Total value that Ray had
= 2620 + 280
= $2900

Number of $100-notes that Ray had
= 2900 ÷ 100
= 29

Answer(s): (a) Jim; (b) $720; (c) 29
