1. There can be multiple triplets: -1,-2,-3 1,2,3 -1,01 etc. Insufficient AD out.
2. -1,-2,-3 -1,0,1 Insufficient
Combining, still we can have -1,-2,-3 and -1,0,1 but in one we get -6 and in another we get 0. Clearly, insufficient
E is the correct choice

For sum to be equal to product, it can’t be -1,0,1

It’s either 1,2,3 or -1,-2,-3

So using S2, it’s -1,-2,-3. Hence, both statements combined are sufficient

It can. Add -1,0,1, we get 0 and the product is surely 0 as we know anything multiplied by 0 is 0.

use formula C(x-cordinate) = {A(x-cordinate)*b+ B(x-cordinate)*a}/(a+b)

considering the point c divides the line in the ratio a:b
