All numbers in a list of six positive integers are less than 8. What is the smallest integer that if added to the list would guarantee that the average becomes greater than 8?

A. 14

B. 35

C. 42

D. 50

E. 51

Let the 6 numbers be - \({n1,n2,n3,n4,n5,n6} < 8\).

Now, we have to find \(n7\)

\(n1 + n2 + n3 + n4 + n5 + n6 + n7 > 56\)

As the passage uses the word

GUARANTEE, we have to keep \({n1,n2,n3,n4,n5,n6}\) to be minimum i.e. each equal to 1.

Hence, \(n7 >50\)
