PSLE Oscar had 14 more one-dollar notes than ten-dollar notes at first. He exchanged $100 worth of ten-dollar notes for one-dollar notes. How many less ten-dollar notes than one-dollar notes did Oscar have after the exchange?
Number |
$1 |
$10 |
Before |
1 u + 14 |
1 u |
Change |
+ 100 |
- 10 |
After |
1 u + 14 + 100 |
1 u - 10 |
Number of ten-dollar notes that Oscar exchanged into one-dollar notes
= 100 ÷ 10
= 10
Number of one-dollar notes that Oscar received from the exchange
= 100 ÷ 1
= 100
Number of less ten-dollar notes than one-dollar notes
= 14 + 100 + 10
= 124
Answer: 124
