PSLE Ahmad spent
49 of his money to buy 5 identical markers. He spent the rest of his money to buy another 6 such markers and 2 identical staplers.
- What fraction of Ahmad's money was spent to buy the 2 staplers? Give your answer in the simplest form.
- For every 3 staplers bought, 1 additional stapler was given free. How many staplers would Ahmad get in total if he were to spend all his money to buy staplers only?
(a)
Cost of 5 markers =
49 of his money
Cost of 1 marker
=
49 ÷ 5
=
49 x
15 =
445 of his money
Fraction of Ahmad's money spent to buy the 6 markers and 2 staplers
= 1 -
49 =
59 Cost of 6 markers
= 6 x
445 =
2445 of his money
Fraction of Ahmad's money spent to buy the 2 staplers
=
59 -
2445 =
2545 -
2445 =
145 (b)
145 of Ahmad's money = 2 staplers
4545 of Ahmad's money = 45 x 2 = 90 staplers
Number of free staplers
= 90 ÷ 3
= 15 r 0
Total number of staplers that Ahmad would get
= 90 + 15
= 105
Answer(s): (a)
145; (b) 105
