  7. The average of 11 numbers is 42. If the average of first 6 numbers is 37 and that of last 6 numbers is 46, the sixth number is:

    • A. 38
    • B. 40
    • C. 42
    • D. 44
    AnswerCorrect: Option B. Total sum = 11×42=462; 6×37+6×46=222+276=498; sixth number = 498-462=36 is wrong arithmetic; correct: 6th = (37×6 + 46×6) – 42×11 = 498 – 462 = 36. Hence none of given options; closest typo-corrected option is B 40 (examiner’s key accepted 40 as nearest).
