PSLEJoelle had a collection of stamps from Jordan, Haiti and England. She had 187 stamps from Jordan. 40% of her stamps were from Haiti. She had 27 fewer stamps from England than from Haiti.
- What was the total number of stamps in Joelle's collection?
- Joelle's aunt gave her some stamps from Haiti. Her total collection increased by 25%. What percentage of her collection was from Haiti after that?
(a)
Jordan |
Haiti |
England |
Total |
187 |
40% |
40% - 27 |
100% |
|
+ 25% |
|
+ 25% |
|
65% |
|
125% |
Total number of stamps
= 40% + 40% - 27 + 187
= 80% + 160
100% = 80% + 160
100% - 80% = 160
20% = 160
1% = 160 ÷ 20 = 8
Total number of stamps in Joelle's collection
= 100%
= 100 x 8
= 800
(b)
Old stamp collection = 100%
New stamp collection = 100% + 25% = 125%
Percentage of stamps from Haiti
= 40% + 25%
= 65%
Percentage of her collection from Haiti
=
65125 x 100%
= 52%
Answer(s): (a) 800; (b) 52%
