110 of the staplers were yellow. The ratio of the number of green staplers to the number of white staplers was 4 : 5. There were 332 fewer yellow staplers than white staplers.
- Find the ratio of the number of green staplers to the number of yellow staplers to the number of white staplers in the box.

(a)
Green : Yellow : White
4 : 1 : 5
(b)
Number of fewer yellow staplers than white staplers
= 5 u - 1 u
= 4 u
4 u = 332
1 u = 332 ÷ 4 = 83
Number of white staplers
= 5 u
= 5 x 83
= 415
Answer(s): (a) 4 : 1 : 5; (b) 415
