Question

The sum of numbers between 100 and 500 , which are divisible by 6 is –

• A. 67
• B. 498
• C. 2010
• D. None

Answer 1

Answer: (D)

None

Answer 2

S = 102 + 108… + 498

$\mathrm { n } = \frac { 498 - 102 } { 6 } + 1 = \frac { 396 } { 6 } + 1 = 67$

S = $\frac { 67 } { 2 }$ (102 + 498) = 300 × 67 = 20100
