PSLE David used
35 of his money to buy 6 staplers. He used the rest of his money to buy 3 staplers and 4 markers.
- What fraction of his money did David use to buy the 4 markers?
- If 1 marker was given for free for every 3 markers bought, how many markers would David be able to buy if he were to use all his money to buy markers?
(a)
Fraction of his money used to buy 3 staplers and 4 markers
= 1 -
35 =
25 6 staplers →
35 of his money
1 pen →
35 ÷ 6 =
110 of his money
3 staplers → 3 x
110 =
310 of his money
3 staplers + 4 markers →
25 of his money
4 markers →
25 -
310 =
410 -
310 =
110 of his money
(b)
4 markers →
1101 marker →
110 ÷ 4 =
140 of his money
If 1 marker cost
140 of his money, David could buy 40 markers (Not including the free ones).
Number of free markers that David could get
= 40 ÷ 3
= 13 r 1
Total number of markers that David could get
= 40 + 13
= 53
Answer(s): (a)
110; (b) 53
