Let

S_n

denote the sum of the cubes of the first

n

natural numbers and

s_n

denote the sum of the first

n

natural numbers. Then,

\sum\limits_{r=1}^n \frac{S_r}{s_r}

is equal to

View answer and explanation

Correct option: C

\left(\frac{n+2}{3}\right) \sum\limits_{r=1}^n r

Option C (

\left(\frac{n+2}{3}\right) \sum\limits_{r=1}^n r

) is correct because it is the simplified form of the sum of the series.
