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