PSLECindy had a collection of stamps from Fiji, Belgium and Korea. She had 194 stamps from Fiji. 40% of her stamps were from Belgium. She had 14 fewer stamps from Korea than from Belgium.
- What was the total number of stamps in Cindy's collection?
- Cindy's aunt gave her some stamps from Belgium. Her total collection increased by 25%. What percentage of her collection was from Belgium after that?
(a)
Fiji |
Belgium |
Korea |
Total |
194 |
40% |
40% - 14 |
100% |
|
+ 25% |
|
+ 25% |
|
65% |
|
125% |
Total number of stamps
= 40% + 40% - 14 + 194
= 80% + 180
100% = 80% + 180
100% - 80% = 180
20% = 180
1% = 180 ÷ 20 = 9
Total number of stamps in Cindy's collection
= 100%
= 100 x 9
= 900
(b)
Old stamp collection = 100%
New stamp collection = 100% + 25% = 125%
Percentage of stamps from Belgium
= 40% + 25%
= 65%
Percentage of her collection from Belgium
=
65125 x 100%
= 52%
Answer(s): (a) 900; (b) 52%
