Hello,

Can you please tell me where I am going wrong here in my solution for Statement 2:

If r is the range of the 6 integers in set S, is r greater than 20?

(1) When ordered from least to greatest, the difference between any two
consecutive integers in S is less than 4.

(2) When ordered from least to greatest, the difference between any two
consecutive integers in S is less than 5.


Let the 6 integers be a, b, c, d, e, f
Range = f - a

Is f - a > 20?

1) b - a < 4
c - b < 4
d - c < 4
e - d < 4
f - e < 4

On adding the above we get f - a < 20. Hence, sufficient

2) b - a < 5
c - b < 5
d - c < 5
e - d < 5
f - e < 5

=> f - e < 25. Hence in-suff.


However, the OA is given as D. Can you please assist? Thanks a lot.


Best Regards,
Sri
