- What was the total number of stamps in Shiyun's collection?
- Shiyun's aunt gave her some stamps from India. Her total collection increased by 25%. What percentage of her collection was from India after that?
(a)
Ireland |
India |
Malta |
Total |
94 |
40% |
40% - 34 |
100% |
|
+ 25% |
|
+ 25% |
|
65% |
|
125% |
Total number of stamps
= 40% + 40% - 34 + 94
= 80% + 60
100% = 80% + 60
100% - 80% = 60
20% = 60
1% = 60 ÷ 20 = 3
Total number of stamps in Shiyun's collection
= 100%
= 100 x 3
= 300
(b)
Old stamp collection = 100%
New stamp collection = 100% + 25% = 125%
Percentage of stamps from India
= 40% + 25%
= 65%
Percentage of her collection from India
=
65125 x 100%
= 52%
Answer(s): (a) 300; (b) 52%
