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. (280, 140) (186, 93)
(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.)
(118, 59)
The pattern in the given pairs involves dividing the first number by 2 to get the second number. For example:
280 ÷ 2 = 140
186 ÷ 2 = 93
Similarly, in the fourth option:
118 ÷ 2 = 59. Hence, the correct answer is 4.
