Questions and formulas:
Question: What is the function percentage when the estimated function percentage is 20?
Formula: LET(query1,SUMMARIZE(D1,SUMX(E1)),FILTER(query1,CHOOSECOLS(query1,2)=20))
Formula2: LET(query1,SUMMARIZE(D2:D7,SUMX(E2:E7)),FILTER(query1,CHOOSECOLS(query1,2)=20))
Level: hard
Question: What is the measurement where the estimated function % is less than 20?
Formula: LET(query1,SUMMARIZE(C1,SUMX(E1)),FILTER(query1,CHOOSECOLS(query1,2)<20))
Formula2: LET(query1,SUMMARIZE(C2:C7,SUMX(E2:E7)),FILTER(query1,CHOOSECOLS(query1,2)<20))
Level: hard
Question: What is the estimated function % when the measurement is 8/8?
Formula: SUMIFS(E1,C1,"8/8")
Formula2: SUMIFS(E2:E7,C2:C7,"8/8")
Level: easy
