PSLEVictoria had a collection of stamps from Thailand, Haiti and Jordan. She had 94 stamps from Thailand. 20% of her stamps were from Haiti. She had 34 fewer stamps from Jordan than from Haiti.
- What was the total number of stamps in Victoria's collection?
- Victoria'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)
Thailand |
Haiti |
Jordan |
Total |
94 |
20% |
20% - 34 |
100% |
|
+ 25% |
|
+ 25% |
|
45% |
|
125% |
Total number of stamps
= 20% + 20% - 34 + 94
= 40% + 60
100% = 40% + 60
100% - 40% = 60
60% = 60
1% = 60 ÷ 60 = 1
Total number of stamps in Victoria's collection
= 100%
= 100 x 1
= 100
(b)
Old stamp collection = 100%
New stamp collection = 100% + 25% = 125%
Percentage of stamps from Haiti
= 20% + 25%
= 45%
Percentage of her collection from Haiti
=
45125 x 100%
= 36%
Answer(s): (a) 100; (b) 36%
