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