PSLEElyse had a collection of stamps from Jordan, Norway and England. She had 194 stamps from Jordan. 30% of her stamps were from Norway. She had 34 fewer stamps from England than from Norway.
- What was the total number of stamps in Elyse's collection?
- Elyse's aunt gave her some stamps from Norway. Her total collection increased by 25%. What percentage of her collection was from Norway after that?
(a)
Jordan |
Norway |
England |
Total |
194 |
30% |
30% - 34 |
100% |
|
+ 25% |
|
+ 25% |
|
55% |
|
125% |
Total number of stamps
= 30% + 30% - 34 + 194
= 60% + 160
100% = 60% + 160
100% - 60% = 160
40% = 160
1% = 160 ÷ 40 = 4
Total number of stamps in Elyse's collection
= 100%
= 100 x 4
= 400
(b)
Old stamp collection = 100%
New stamp collection = 100% + 25% = 125%
Percentage of stamps from Norway
= 30% + 25%
= 55%
Percentage of her collection from Norway
=
55125 x 100%
= 44%
Answer(s): (a) 400; (b) 44%
