Questions and formulas:
Question: Clock rate (MHz) smaller than 400, and a Bandwidth (MB/s) of 1420 has what channels?
Formula: LET(query1,SUMMARIZE(C1,SUMX(D1),SUMX(E1)),FILTER(query1,(CHOOSECOLS(query1,2)<400)*(CHOOSECOLS(query1,3)=1420)))
Formula2: LET(query1,SUMMARIZE(C2:C10,SUMX(D2:D10),SUMX(E2:E10)),FILTER(query1,(CHOOSECOLS(query1,2)<400)*(CHOOSECOLS(query1,3)=1420)))
Level: hard
Question: Bandwidth (MB/s) smaller than 4800, and a Bus width (bits) smaller than 16 has what highest Clock rate (MHz)?
Formula: MAX(FILTER(D1, (E1<4800)*(B1<16)))
Formula2: MAX(FILTER(D2:D10, (E2:E10<4800)*(B2:B10<16)))
Level: easy
