  1. If a, b, c, d, e are five consecutive odd number , their average is ?
    1. 5 (a + 4)
    2. abcd/5
    3. 5 (a + b + c + d + e)
    4. None of these
  1. Correct Option: D

    Since a, b, c, d, e are 5 consecutive numbers so
    b = a + 2.
    c = a + 4.
    d = a + 6.
    e = a + 8.

    Average = (a + b + c + d + e)/ 5
    = [a + (a + 2 ) + (a +4 ) + (a+6 )+ (a+8)] / 5
    = (5a+20) / 5
    = a + 4
