4)

44 is related to 1936 by certain logic. Following the same logic, 59 is related to 3481. To
which of the following is 77 related, following the same logic? (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 /deleting /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.) 

5)

Select the set in which the numbers are related in the same way as are the numbers of
the following set.
(34, 17, 27)
(42, 21, 31)

(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/deleting/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.

6)

In a certain code language,
‘A + B’ means ‘A is the mother of B’;
‘A – B’ means ‘A is the husband of B’;
‘A × B’ means ‘A is the father of B’ and
‘A ÷ B’ means ‘A is the daughter of B’.

Based on the above, how is K  related to O if ‘K ÷ L − M + N × O’

7)

Select the set in which the numbers are related in the same way as are the numbers of
the following set.
3 — 5 — 30
2 — 4 — 16NOTE: 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 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

8)

Select the option that represents the letters which, when sequentially placed from left
to right in the blanks below, will complete the letter series.
f d _ e _ e f _ d d _ d _ f f _ d _ d _ f

9)

Three of the following number-pairs are alike in some manner and hence form a group.
Which number-pair does not belong to that group?

(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.)
