PSLE Carl used
47 of his money to buy 8 staplers. He used the rest of his money to buy 5 staplers and 4 markers.
- What fraction of his money did Carl use to buy the 4 markers?
- If 1 marker was given for free for every 6 markers bought, how many markers would Carl be able to buy if he were to use all his money to buy markers?
(a)
Fraction of his money used to buy 5 staplers and 4 markers
= 1 -
47 =
37 8 staplers →
47 of his money
1 pen →
47 ÷ 8 =
114 of his money
5 staplers → 5 x
114 =
514 of his money
5 staplers + 4 markers →
37 of his money
4 markers →
37 -
514 =
614 -
514 =
114 of his money
(b)
4 markers →
1141 marker →
114 ÷ 4 =
156 of his money
If 1 marker cost
156 of his money, Carl could buy 56 markers (Not including the free ones).
Number of free markers that Carl could get
= 56 ÷ 6
= 9 r 2
Total number of markers that Carl could get
= 56 + 9
= 65
Answer(s): (a)
114; (b) 65
