The average weekly number of toy helicopters produced by Factory A and B is 3532. The average weekly number of toy helicopters produced by Factory A and C is 7033. If Factory B produced ²₅ as many toy helicopters as Factory C each week, how many toy helicopters does Factory A produce weekly?
Total toy helicopters that Factory A and Factory B produced
= 3532 x 2
= 7064

Total toy helicopters that Factory A and Factory C produced
= 7033 x 2
= 14066

Number of toy helicopters produced by Factory B = 2 u
Number of toy helicopters produced by Factory C = 5 u

Factory A's toys + 2 u = 7064 --- (1)
Factory A's toys + 5 u = 14066 --- (2)

(2) - (1)
5 u - 2 u = 14066 - 7064
3 u = 7002
1 u = 7002 ÷ 3 = 2334

Number of toy helicopters produced by B
= 2 u
= 2 x 2334
= 4668

Number of toy helicopters produced by A
= 7064 - 4668
= 2396

Answer(s): 2396
