The pie charts show the number of each type of stationery in 2 stationery boxes, N and P. The total number of stationery in Box N is twice the total number of stationery in Box P.

1. Find the percentage of markers in Box N.
2. What fraction of stationery in Box P is markers?
3. The number of markers in Box N is 140. Find the number of markers in Box P.

(a)
^90°_360° = 25% of stationery in Box N

Percentage of highlighters in Box N = 25%

Percentage of markers in Box N
= 100% - 40% - 25%
= 35%

(b)
Percentage of markers in Box P
= 100% - 45% - 30%
= 25%

Fraction of stationery in Box P that is markers
= ¹₄

(c)
35% of stationery in Box N = 140
1% of stationery in Box N = 140 ÷ 35 = 4 
100% of the stationery in Box N = 100 x 4 = 400

Number of stationery in Box P
= 400 ÷ 2
= 200

100% of stationery in Box P = 200
1% of stationery in Box N = 200 ÷ 100 = 2
25% of stationery in Box N = 25 x 2 = 50  

Number of markers in Box P = 50

Answer(s): (a) 35%; (b) ¹₄; (c) 50
