PSLE Tom used
35 of his money to buy 6 pens. He used the rest of his money to buy 3 pens and 2 markers.
- What fraction of his money did Tom use to buy the 2 markers?
- If 1 marker was given for free for every 3 markers bought, how many markers would Tom be able to buy if he were to use all his money to buy markers?
(a)
Fraction of his money used to buy 3 pens and 2 markers
= 1 -
35 =
25 6 pens →
35 of his money
1 pen →
35 ÷ 6 =
110 of his money
3 pens → 3 x
110 =
310 of his money
3 pens + 2 markers →
25 of his money
2 markers →
25 -
310 =
410 -
310 =
110 of his money
(b)
2 markers →
1101 marker →
110 ÷ 2 =
120 of his money
If 1 marker cost
120 of his money, Tom could buy 20 markers (Not including the free ones).
Number of free markers that Tom could get
= 20 ÷ 3
= 6 r 2
Total number of markers that Tom could get
= 20 + 6
= 26
Answer(s): (a)
110; (b) 26
