PSLE Vaidev used
23 of his money to buy 6 markers. He used the rest of his money to buy 2 markers and 5 files.
- What fraction of his money did Vaidev use to buy the 5 files?
- If 1 file was given for free for every 4 files bought, how many files would Vaidev be able to buy if he were to use all his money to buy files?
(a)
Fraction of his money used to buy 2 markers and 5 files
= 1 -
23 =
13 6 markers →
23 of his money
1 pen →
23 ÷ 6 =
19 of his money
2 markers → 2 x
19 =
29 of his money
2 markers + 5 files →
13 of his money
5 files →
13 -
29 =
39 -
29 =
19 of his money
(b)
5 files →
191 file →
19 ÷ 5 =
145 of his money
If 1 file cost
145 of his money, Vaidev could buy 45 files (Not including the free ones).
Number of free files that Vaidev could get
= 45 ÷ 4
= 11 r 1
Total number of files that Vaidev could get
= 45 + 11
= 56
Answer(s): (a)
19; (b) 56
