Explanation

Now we have average of a, b, c, d, e is 100.

\(\frac{a+b+c+d+e}{5}= 100\) or \(a+b+c+d+e= 500\).

for a to be least b, c, d and e must be maximum. Now b, c, d and e can take a maximum values 110 each as \(b \leq c \leq d \leq e\).

\(a + 110 + 110 + 110 + 110 = 500\)

\(a = 60.\)

Hence option D is correct.
