the average of 11 result is 50. If the average of first-six results is 49 and that of last six is 52, find the sixth result​

  1. Answer:

    78.45

    Step-by-step explanation:

    Let us assume the total marks to be 100. Now,

    From test, marks are 75% of 76 = 0.75 * 76 = 57—————-(A)

    From quiz, marks are 20% of 85 = 0.2 * 85 = 17——————(B)

    From homework, marks are 5% of 89 = 0.05 * 89 = 4.45—–(C)

    Now,

    A + B + C = 78.45
