Questions and formulas:
Question: What is the max speed of the unit with an 8+4 quantity built before 1971?
Formula: SUM(FILTER(F1, (D1="8+4")*(C1<1971)))
Formula2: SUM(FILTER(F2:F8, (D2:D8="8+4")*(C2:C8<1971)))
Level: easy
Question: What is the numbers of the thn unit with a power greater than 220?
Formula: LET(query1,LET(query1,FILTER(A1:F1,A1="thn"),SUMMARIZE(CHOOSECOLS(query1,2),SUMX(CHOOSECOLS(query1,5)))),FILTER(query1,CHOOSECOLS(query1,2)>220))
Formula2: LET(query1,LET(query1,FILTER(A2:F8,A2:A8="thn"),SUMMARIZE(CHOOSECOLS(query1,2),SUMX(CHOOSECOLS(query1,5)))),FILTER(query1,CHOOSECOLS(query1,2)>220))
Level: hard
