PSLE Asher spent
37 of his money to buy 4 identical files. He spent the rest of his money to buy another 5 such files and 2 identical staplers.
- What fraction of Asher's money was spent to buy the 2 staplers? Give your answer in the simplest form.
- For every 6 staplers bought, 1 additional stapler was given free. How many staplers would Asher get in total if he were to spend all his money to buy staplers only?
(a)
Cost of 4 files =
37 of his money
Cost of 1 file
=
37 ÷ 4
=
37 x
14 =
328 of his money
Cost of 5 files
= 5 x
328 =
1528 of his money
Fraction of Asher's money spent to buy the 5 files and 2 staplers
= 1 -
37 =
47 Fraction of Asher's money spent to buy the 2 staplers
=
47 -
1528 =
1628 -
1528 =
128 (b)
128 of Asher's money = 2 staplers
2828 of Asher's money = 28 x 2 = 56 staplers
Number of free staplers
= 56 ÷ 6
= 11 r 1
Total number of staplers that Asher would get
= 56 + 11
= 67
Answer(s): (a)
128; (b) 67
