The average weekly number of toy planes produced by Factory V and W is 3809. The average weekly number of toy planes produced by Factory V and X is 6335. If Factory W produced ⁴₇ as many toy planes as Factory X each week, how many toy planes does Factory V produce weekly?
Total toy planes that Factory V and Factory W produced
= 3809 x 2
= 7618

Total toy planes that Factory V and Factory X produced
= 6335 x 2
= 12670

Number of toy planes produced by Factory W = 4 u
Number of toy planes produced by Factory X = 7 u

Factory V's toys + 4 u = 7618 --- (1)
Factory V's toys + 7 u = 12670 --- (2)

(2) - (1)
7 u - 4 u = 12670 - 7618
3 u = 5052
1 u = 5052 ÷ 3 = 1684

Number of toy planes produced by W
= 4 u
= 4 x 1684
= 6736

Number of toy planes produced by V
= 7618 - 6736
= 882

Answer(s): 882
