Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which is the letter-cluster that DOES NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)

In a certain code language,
‘A ? B’ means ‘A is the daughter of B’
‘A = B’ means ‘A is the son of B’
‘A @ B’ means ‘A is the father of B’
‘A √ B’ means ‘ A is the sister of B’
Based on the above, how is C related to L if 'C ? D √ E = F @ L'?

Refer to the following series and answer the question (all numbers are single-digit numbers only). Counting to be done from left to right only.

(Left) 9 2 1 4 2 2 8 3 7 6 7 5 2 4 8 9 7 1 2 3 8 9 2 2 6 2 8 (Right)

How many such odd numbers are there, each of which is immediately preceded by an odd number and also immediately followed by an even number?

L, M, N, O, P and Q are sitting around a circular table facing the centre. M sits second to the left of P. N sits second to the right of Q. O is on the immediate left of M. Who is sitting on the immediate right of L?

Which of the following letter-number clusters will replace the question mark in the given series to make it logically complete?

HO22 JQ31 LS40 NU49 ?

Select the set in which the numbers are related in the same way as are the numbers of the following sets.

(Note: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding / subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

(15, 75, 5)
(12, 36, 3)
