DIRECTION: Study the following letter-number arrangement and answer the questions given below:

B 8 4 C R M 9 P D K W F A 2 E J 7 X U Q H L T Y 6 G S

Which of the following will come in place of the question mark (?) in the following sequence with reference to the above arrangement?

BRC, 8MR, 49M, ?

Given:

B 8 4 C R M 9 P D K W F A 2 E J 7 X U Q H L T Y 6 G S

BRC, 8MR, 49M, ?

Conclusions:

BRC, 8MR, 49M, ?

The following pattern follows as,

B 8 4 C R M 9 P D K W F A 2 E J 7 X U Q H L T Y 6 G S - BRC

B 8 4 C R M 9 P D K W F A 2 E J 7 X U Q H L T Y 6 G S - 8MR

B 8 4 C R M 9 P D K W F A 2 E J 7 X U Q H L T Y 6 G S - 49M

B 8 4 C R M 9 P D K W F A 2 E J 7 X U Q H L T Y 6 G S - CP9

So, the missing letter-number will be CP9.

Hence, the answer is CP9.
