PSLE Japheth used
47 of his money to buy 12 staplers. He used the rest of his money to buy 8 staplers and 5 files.
- What fraction of his money did Japheth use to buy the 5 files?
- If 1 file was given for free for every 6 files bought, how many files would Japheth be able to buy if he were to use all his money to buy files?
(a)
Fraction of his money used to buy 8 staplers and 5 files
= 1 -
47 =
37 12 staplers →
47 of his money
1 pen →
47 ÷ 12 =
121 of his money
8 staplers → 8 x
121 =
821 of his money
8 staplers + 5 files →
37 of his money
5 files →
37 -
821 =
921 -
821 =
121 of his money
(b)
5 files →
1211 file →
121 ÷ 5 =
1105 of his money
If 1 file cost
1105 of his money, Japheth could buy 105 files (Not including the free ones).
Number of free files that Japheth could get
= 105 ÷ 6
= 17 r 3
Total number of files that Japheth could get
= 105 + 17
= 122
Answer(s): (a)
121; (b) 122
