571+572+573 = 3*572 = 3*(2^2*11*13) = 11*12*13 --> 11+12+13 = 36.

Answer: E.

P.S. Please provide OA's for the questions.

Addition of any 3 consecutive numbers is always divisible by 3

So, options A, C , D are ruled out

Now focus on options 33 & 36

It can be either

10, 11, 12 (Gives zero at the end after multiplication; ignore this series)

or

11, 12, 13 (Matches fine)

Answer = E

E. 36

$$=571+572+573=1716=(13)(11)(2)(2)(3)$$

after seeing 11 and 13, I knew the third should be 12 without calculating rem. factors.

$$=11+12+13= 36$$

Answer: E
