Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Even multiples of 9 are multiples of 18.
Step 1: Find limits.
\[ 18 \times 17 = 306,\quad 18 \times 27 = 486 \]
Step 2: AP.
\[ 306, 324, \dots, 486 \] \[ n = 11 \]
Step 3: Sum.
\[ S = \frac{11}{2}(306+486) = 4356 \]
Step 1: Find limits.
\[ 18 \times 17 = 306,\quad 18 \times 27 = 486 \]
Step 2: AP.
\[ 306, 324, \dots, 486 \] \[ n = 11 \]
Step 3: Sum.
\[ S = \frac{11}{2}(306+486) = 4356 \]
