Logical Reasoning - Letter and Symbol Series - Discussion

Because all numbers are moving in circular path.

First number 2 on B (i.e B2Cd) , then it get incremented by one i.e. 3 moves to next alphabet (i.e C) form BC3D (Ans). Then again number get incremented by one i.e 4 moves to next alphabet (i.e D) form BCD4, Now Here Alphabet are Three only (B, C, D) which are in circular form (means After D here B will come) , again numbers moves to 1st alphabet i.e 'B' Hence next incremented number get moved to B (i.e B5CD) by this way After BC6D number will come BCD7 (In Advanced).

Very nice and I understanding this logic its good thanks.

Thanks @Anusha.

Base values are in the order of 4, ---, 6, 7, 8 find the base value of 5 from the options.

B2CD, _BC3D_, BCD4 = in B2CD B has number 2, in BCD4 D has a number 4 C has no number so answer is BC3D. The series of the number is 2, 3, 4.

B2 has 2 in first set of words, C has missing number so we have entered 3 for C in second set of words i.e., C3, D4 in third set of words.

Hai friends I got the answer.

I can't understand this logic.

@Rubini tell me about the your answer.

First number B2CD = B + B + C + D = 4 "B2". First series start with 2.

Second number BC3D = B + C + C + C +D = 5 "C3". Second series Sequence 3.

Third Numbr BCD4 = B + C + D + D + D + D = 6 "D4" Third Series sequence 4.

Fourth Number B5CD = B + B + B + B + B + C + D =7 "B5" Alternator continue with number 5.

Fifth number BC6D =B +C + C + C + C + C + C + D =8 "C6" This the sequence with 6.

On this letter series the number will take b to c, and c to d, and again d to b like triangle wise. So first, b series they had been mentioned the substring of 2. So, what will happen, next to b, c series will get the next process, after that d, next c.
