In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. 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 37, 62
the numbers into their constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
52, 77
To find the correct set, we first determine the mathematical relationship (the pattern) in the given sets:
Analyzing the Given Sets:
First Set: (37, 62)
$62 - 37 = 25$
Second Set: (52, 77)
$77 - 52 = 25$
The Pattern: The second number is obtained by adding 25 to the first number.
Evaluating the Options:
81, 96: $96 - 81 = 15$ (Incorrect)
69, 88: $88 - 69 = 19$ (Incorrect)
64, 84: $84 - 64 = 20$ (Incorrect)
46, 71: $71 - 46 = 25$ (Correct)
The set (46, 71) follows the same logic as the example sets.
Important Questions from Number Series
- In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Which numbers should replace X and Y so that the pattern followed by the two numbers on the left side of :: is the same as that on the right side of :: ?
(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.)
