Questions and formulas:
Question: What are the works numbers where the year is 1929 and the driver diameter is 60/1520mm? 
Formula: SUM(FILTER(D1, (C1=1929)*(F1="60/1520mm")))
Formula2: SUM(FILTER(D2:D20, (C2:C20=1929)*(F2:F20="60/1520mm")))
Level: easy
Question: For what year is the SAR no. 874?
Formula: LET(query1,SUMMARIZE(C1,SUMX(A1)),FILTER(query1,CHOOSECOLS(query1,2)=874))
Formula2: LET(query1,SUMMARIZE(C2:C20,SUMX(A2:A20)),FILTER(query1,CHOOSECOLS(query1,2)=874))
Level: hard
