PSLEFiona had a collection of stamps from Jordan, France and Kenya. She had 108 stamps from Jordan. 30% of her stamps were from France. She had 28 fewer stamps from Kenya than from France.
- What was the total number of stamps in Fiona's collection?
- Fiona's aunt gave her some stamps from France. Her total collection increased by 25%. What percentage of her collection was from France after that?
(a)
Jordan |
France |
Kenya |
Total |
108 |
30% |
30% - 28 |
100% |
|
+ 25% |
|
+ 25% |
|
55% |
|
125% |
Total number of stamps
= 30% + 30% - 28 + 108
= 60% + 80
100% = 60% + 80
100% - 60% = 80
40% = 80
1% = 80 ÷ 40 = 2
Total number of stamps in Fiona's collection
= 100%
= 100 x 2
= 200
(b)
Old stamp collection = 100%
New stamp collection = 100% + 25% = 125%
Percentage of stamps from France
= 30% + 25%
= 55%
Percentage of her collection from France
=
55125 x 100%
= 44%
Answer(s): (a) 200; (b) 44%
