This is the first time I am posting a question. I tried to incorporate all the rules. Let me know if I violated any.

I searched but didn't find this question online.

K1 K2 K3 K4 K5 K6 K7 K8 K9

K5 = K4 + K3 = 18
K9 = K7 + K8 = ?


Statement 1: K4 = 11
Using K4 and K5 we can find K6, then K7 and so on.

This statement is sufficient.

Statement 2: K6 = 29
Using K5 and K6 we can find K7, then K8 and so on.

This statement is sufficient.

Answer is D

Ans D.
k 5 = 18 --> k4 + k3 = k5

1) K 4 = 11
K4 +K3 = K5--> k3 = 18 -11
SUFF

2) K 6 = 29
K 6 = K5 + K 4
29 = 18 + K 4
K 4 = 11

SUFF
