The average weight of A, B and C is 45 Kg, If the average weight of A and B be 40 Kg and that of B and C be 43 Kg then the weight of B is:

  • 16 Kg
  • 31 Kg
  • 20 Kg
  • 17 Kg
  • b
  • Total Weight of A,B & C = 45
    Weight of Single One = 45*3=135
    Total Weight of A & B = 40
    Weight of Single One = 40.*2=80
    Total weight of B & C = 43
    Weight of Single One = 43*2=86
    A + B + C = 135
    80+C=135
    C=135-80=55
    B+C = 86
    B+55=86

The age of Sohail , Afzal and Bilal are 17,16 and 12 respectively, if the age of Aslam also included the average of the ages increases by 5. What is the age of Aslam?

  • 33
  • 34
  • 35
  • 36
  • c
  • Average formula = (A+B+C)/03
    17+16+12=45
    45/3=15 Years (Average Age)
    15+5=20 Years (Average after 05 Years increase)
    Suppose, Aslam Age = X

    Average formula = (A+B+C)/03
    17+16+12=45
    45/3=15 Years (Average Age)
    15+5=20 Years (Average after 05 Years increase)
    Suppose, Aslam Age = X
    Average of All are= (17+16+12+X)/4=20
    (45+X)4=20
    45+X=20*4
    45+ X=80
    X=80-45=35

    Average of All are= (17+16+12+X)/4=20
    (45+X)4=20
    45+X=20*4
    45+ X=80
    X=80-45=35
