In the following question, four 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 odd one out 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 mathematical operations on 1 and 3 is not allowed)

Answer 1

The pattern followed here is:

Logic: (First number × 4) - 4 = Second number.

Let's check each option one by one.

Option 1) 15 - 56

⇒ (15 × 4) - 4

⇒ 60 - 4 = 56

Option 2) 13 - 48

⇒ (13 × 4) - 4

⇒ 52 - 4 = 48

Option 3) 11 - 39

⇒ (11 × 4) - 4

⇒ 44 - 4 = 40 ≠ 39.

Option 4) 17 - 64

⇒ (17 × 4) - 4

⇒ 68 - 4 = 64

Hence, the correct answer is "Option 3".
