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 their constituent digits. E.g. 13 – Operations on 13 such as adding to/subtracting from/multiplying with 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Which of the following letter-clusters should replace # and % so that the pattern and relationship followed between the letter-cluster pair on the left side of :: is the same as the pattern and relationship followed between the letter-cluster pair on the right side of ::?

SBM : # :: % : GOD

Select the pair that follows the same pattern as that followed by the two pairs given below. Both pairs follow the same pattern.

ZQB : CSC

OIF : RKG

Two sets of numbers are given below. In each set of numbers, certain mathematical operation(s) on the first number result(s) in the second number. Similarly, certain mathematical operation(s) on the second number result(s) in the third number and so on. Which of the given options follows the same set of operations as in the given sets?

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

17 - 34 - 68 - 98;

21 - 42 - 84 - 114

Two sets of numbers are given below. In each set of numbers, performing a certain mathematical operation on the first number gives the second number. Similarly, performing a certain mathematical operation on the second number gives the third number. Which of the given options follows the same set of operations as used in the given sets?

(Note: Two/three-digit numbers cannot be broken into individual digits for the operations. For example, if 37 is followed by 10, the operation cannot be 3+7 because a two-digit number cannot be broken into individual digits.)

145 - 725 - 404 ;

159 - 795 - 474

Based on the English alphabetical order, MKRO is related to SQXU in a certain way. In the same way, JHOL is related to PNUR. Following the same logic, ECJG is related to which of the following?

35 is related to 283 following a certain logic. Following the same logic, 27 is related to 219. To which of the following is 41 related, following the same logic?

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their 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.)

Which of the following letter-clusters should replace # and % so that the pattern and relationship followed between the letter-cluster pair on the left side of :: is the same as that on the right side of ::?

# : LMN :: STU : %

Which of the following letter-clusters should replace # and % so that the pattern and relationship followed between the letter-cluster pair on the left side of :: is the same as that on the right side of :: ?

# : PLQ :: LHM : %

Select the option that is related to the third term in the same way as the second term is related to the first term.
