Information given: - Yesterday, number of songs streamed was 3x number of podcasts streamed
Question:- Was platform's revenue from song streams greater than its revenue from podcast streams?
Solution:- Number of podcasts = P, number of songs = 3P
- Average revenue per podcast stream = p, average revenue per song stream = s
- Revenue from podcasts: P * p
- Revenue from songs: 3P * s
- Since P > 0, question becomes whether 3s > p
- Statement 1: The average (arithmetic mean) revenue earned per podcast stream on the platform yesterday was 12 cents more than the average revenue earned per song stream on the platform yesterday.
- p = s + 12, 3s > s + 12?
- If s > 6, then 3s > p, revenue from songs would be greater
- If s = 6, then p = 18 and 3s = 18, revenues would be equal
- Statement 1 is not sufficient
- Statement 2: Yesterday, the average revenue per stream, calculated across both songs and podcasts, exceeded 20 cents.
- Combined average: (3P*s + P*p)/4P > 20
- (3s + p)/4 > 20
- (3s + p)/80
- Many combinations are possible, does not fix whether 3s > p
- Statement 2 is not sufficient
- Statement 1 and 2 combined
- 3s + (s+12) > 80, 4s > 68, s > 17
- 2s>12 and s>17
- So, s>17 and s>6 is always true
- Together, they guarantee answer is yes
Answer: C, both statement together are sufficient, but neither aloneBunuel
