PSLEHazel had a collection of stamps from Pakistan, Italy and Fiji. She had 196 stamps from Pakistan. 40% of her stamps were from Italy. She had 16 fewer stamps from Fiji than from Italy.
- What was the total number of stamps in Hazel's collection?
- Hazel's aunt gave her some stamps from Italy. Her total collection increased by 20%. What percentage of her collection was from Italy after that?
(a)
Pakistan |
Italy |
Fiji |
Total |
196 |
40% |
40% - 16 |
100% |
|
+ 20% |
|
+ 20% |
|
60% |
|
120% |
Total number of stamps
= 40% + 40% - 16 + 196
= 80% + 180
100% = 80% + 180
100% - 80% = 180
20% = 180
1% = 180 ÷ 20 = 9
Total number of stamps in Hazel's collection
= 100%
= 100 x 9
= 900
(b)
Old stamp collection = 100%
New stamp collection = 100% + 20% = 120%
Percentage of stamps from Italy
= 40% + 20%
= 60%
Percentage of her collection from Italy
=
60120 x 100%
= 50%
Answer(s): (a) 900; (b) 50%
