- What was the total number of stamps in Lynn's collection?
- Lynn's aunt gave her some stamps from Pakistan. Her total collection increased by 25%. What percentage of her collection was from Pakistan after that?
(a)
France |
Pakistan |
Denmark |
Total |
121 |
40% |
40% - 41 |
100% |
|
+ 25% |
|
+ 25% |
|
65% |
|
125% |
Total number of stamps
= 40% + 40% - 41 + 121
= 80% + 80
100% = 80% + 80
100% - 80% = 80
20% = 80
1% = 80 ÷ 20 = 4
Total number of stamps in Lynn's collection
= 100%
= 100 x 4
= 400
(b)
Old stamp collection = 100%
New stamp collection = 100% + 25% = 125%
Percentage of stamps from Pakistan
= 40% + 25%
= 65%
Percentage of her collection from Pakistan
=
65125 x 100%
= 52%
Answer(s): (a) 400; (b) 52%
