    Question

    In the following question, five number pairs are given.

    In each pair the number on left side of (-) is related to the number of the right side of (-) with some Logic/Rule/Relation. Three pairs are similar on basis of same Logic/Rule/Relation. Select the ESIC Part B from the given alternatives. (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 ESIC Part Bs on 1 and 3 is not allowed).
    A 32 – 158 Correct Answer Incorrect Answer
    B 22 - 142 Correct Answer Incorrect Answer
    C 54 – 268 Correct Answer Incorrect Answer
    D 33 – 163 Correct Answer Incorrect Answer
    E 21 – 101 Correct Answer Incorrect Answer

    Solution

    The logic followed here is: 2nd number = 5 X 1st number – 2 32 – 158 → 5 x 32 – 2 = 160 – 2 = 158. 22 - 142 → 5 x 22 – 2 = 110 – 2 = 108. 54 – 268 → 5 x 54 – 2 = 270 – 2 = 268. 33 – 163→ 5 x 33 – 2 = 165 – 2 = 163. 21 – 101 → 5 x 21 – 2 = 105 – 2 = 103.
