C.
4.5
D.
4.7

Answer: Option A

Solution

Answer: Option A
Solution:
Let the six number be a, b, c, d, e, f
According to the question,
    = 3.95
⇒ a + b + c + d + e + f = 23.7.....(i)
  = 3.4
⇒ a + b = 6.8.....(ii)
  = 3.85
⇒ c + d = 7.7.....(iii)
Put the value of equation (ii) and equation (iii) in equation (i)
e + f = 23.7 - 7.7 - 6.8
e + f = 9.2
∴ Average = = 4.6
