PSLEKylie had a collection of stamps from Belgium, Spain and Japan. She had 89 stamps from Belgium. 40% of her stamps were from Spain. She had 29 fewer stamps from Japan than from Spain.
- What was the total number of stamps in Kylie's collection?
- Kylie's aunt gave her some stamps from Spain. Her total collection increased by 25%. What percentage of her collection was from Spain after that?
(a)
Belgium |
Spain |
Japan |
Total |
89 |
40% |
40% - 29 |
100% |
|
+ 25% |
|
+ 25% |
|
65% |
|
125% |
Total number of stamps
= 40% + 40% - 29 + 89
= 80% + 60
100% = 80% + 60
100% - 80% = 60
20% = 60
1% = 60 ÷ 20 = 3
Total number of stamps in Kylie's collection
= 100%
= 100 x 3
= 300
(b)
Old stamp collection = 100%
New stamp collection = 100% + 25% = 125%
Percentage of stamps from Spain
= 40% + 25%
= 65%
Percentage of her collection from Spain
=
65125 x 100%
= 52%
Answer(s): (a) 300; (b) 52%
