Solution(By ExamCraze Team)

Let the six number be a, b, c, d, e, f
According to the question,
⇒ $$frac{a + b + c + d + e + f}{6}$$     = 3.95
⇒ a + b + c + d + e + f = 23.7.....(i)
$$frac{a + b}{2}$$  = 3.4
⇒ a + b = 6.8.....(ii)
$$frac{c + d}{2}$$  = 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 =$$frac{9.2}{2}$$ = 4.6
