Questions and formulas:
Question: What is the highest up:down ratio with 4 mbit/s upstream?
Formula: MAXIFS(D1,C1,"4 mbit/s")
Formula2: MAXIFS(D2:D9,C2:C9,"4 mbit/s")
Level: easy
Question: What is the upstream with a 150 gb monthly cap?
Formula: UNIQUE(CHOOSECOLS(FILTER(A1:F1,E1="150 gb"),3))
Formula2: UNIQUE(CHOOSECOLS(FILTER(A2:F9,E2:E9="150 gb"),3))
Level: medium
Question: What is the upstream with an up:down ratio of 0.03 and a 150 gb monthly cap?
Formula: LET(query1,LET(query1,FILTER(A1:F1,E1="150 gb"),SUMMARIZE(CHOOSECOLS(query1,3),SUMX(CHOOSECOLS(query1,4)))),FILTER(query1,CHOOSECOLS(query1,2)=0.03))
Formula2: LET(query1,LET(query1,FILTER(A2:F9,E2:E9="150 gb"),SUMMARIZE(CHOOSECOLS(query1,3),SUMX(CHOOSECOLS(query1,4)))),FILTER(query1,CHOOSECOLS(query1,2)=0.03))
