PSLEThe pie charts show the number of each type of stationery in 2 stationery boxes, F and G. The total number of stationery in Box F is five times the total number of stationery in Box G.
- Find the percentage of files in Box F.
- What fraction of stationery in Box G is files?
- The number of files in Box F is 400. Find the number of files in Box G.
(a)
90°360° = 25% of stationery in Box F
Percentage of correction tapes in Box F = 25%
Percentage of files in Box F
= 100% - 35% - 25%
= 40%
(b)
Percentage of files in Box G
= 100% - 35% - 30%
= 35%
Fraction of stationery in Box G that is files
= 35100
=
720 (c)
40% of stationery in Box F = 400
1% of stationery in Box F = 400 ÷ 40 = 10
100% of the stationery in Box F = 100 x 10 = 1000
Number of stationery in Box G
= 1000 ÷ 5
= 200
100% of stationery in Box G = 200
1% of stationery in Box F = 200 ÷ 100 = 2
35% of stationery in Box F = 35 x 2 = 70
Number of files in Box G = 70
Answer(s): (a) 40%; (b)
720; (c) 70
