Question

The sum of first $60$ natural numbers is-

• A. $1830$
• B. $1640$
• C. $3660$
• D. $1770$

Answer 1

The correct option is A $1830$

$\Rightarrow$ Here, $n=60$

We know, sum of the first $n$ natural numbers $=\frac{n(n+1)}{2}$

$\therefore$ Sum of first $60$ natural numbers $=\frac{60(60+1)}{2}$

$\therefore$ Sum of first $60$ natural numbers $=\frac{60\times 61}{2}$

$\therefore$ Sum of first $60$ natural numbers $=\frac{3660}{2}$

$\therefore$ Sum of first $60$ natural numbers $=1830$.
