The average number of views per song for S1, S2 and S3 is 100. The average number of views per song for S4, S5 and S6 is 50. What is the total number of views for all the songs sung by all of the 6 different singers taken together?
The average number of views per song for S1, S2 and S3 is 100.
Total number of songs sung by singers S1, S2 and S3 = 20+25+15 = 60
total number of views for all the songs sung by singers S1, S2 and S3 = $$100\times60$$ = 6000
The average number of views per song for S4, S5 and S6 is 50.
Total number of songs sung by singers S4, S5 and S6 = 10+30+20 = 60
total number of views for all the songs sung by singers S4, S5 and S6 = $$50\times60$$ = 3000
Total number of views for all the songs sung by all of the 6 different singers taken together = 6000+3000
= 9000
