PSLEThe pie charts show the number of each type of stationery in 2 stationery boxes, G and H. The total number of stationery in Box G is thrice the total number of stationery in Box H.
- Find the percentage of markers in Box G.
- What fraction of stationery in Box H is markers?
- The number of markers in Box G is 135. Find the number of markers in Box H.
(a)
90°360° = 25% of stationery in Box G
Percentage of highlighters in Box G = 25%
Percentage of markers in Box G
= 100% - 30% - 25%
= 45%
(b)
Percentage of markers in Box H
= 100% - 50% - 15%
= 35%
Fraction of stationery in Box H that is markers
= 35100
=
720 (c)
45% of stationery in Box G = 135
1% of stationery in Box G = 135 ÷ 45 = 3
100% of the stationery in Box G = 100 x 3 = 300
Number of stationery in Box H
= 300 ÷ 3
= 100
100% of stationery in Box H = 100
1% of stationery in Box G = 100 ÷ 100 = 1
35% of stationery in Box G = 35 x 1 = 35
Number of markers in Box H = 35
Answer(s): (a) 45%; (b)
720; (c) 35
