PSLE Vincent used
35 of his money to buy 6 files. He used the rest of his money to buy 3 files and 5 pens.
- What fraction of his money did Vincent use to buy the 5 pens?
- If 1 pen was given for free for every 6 pens bought, how many pens would Vincent be able to buy if he were to use all his money to buy pens?
(a)
Fraction of his money used to buy 3 files and 5 pens
= 1 -
35 =
25 6 files →
35 of his money
1 pen →
35 ÷ 6 =
110 of his money
3 files → 3 x
110 =
310 of his money
3 files + 5 pens →
25 of his money
5 pens →
25 -
310 =
410 -
310 =
110 of his money
(b)
5 pens →
1101 pen →
110 ÷ 5 =
150 of his money
If 1 pen cost
150 of his money, Vincent could buy 50 pens (Not including the free ones).
Number of free pens that Vincent could get
= 50 ÷ 6
= 8 r 2
Total number of pens that Vincent could get
= 50 + 8
= 58
Answer(s): (a)
110; (b) 58
