Practicing Success
In the following question, four number pairs are given. In each pair the umber on the left side of (-) is related to the number on 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) |
19 - 364 21 - 444 17 - 292 13 - 174 |
13 - 174 |
THE LOGIC; 1) 19 - 364, 19 x 2 + 3 = 364 2) 21 - 444, 21 x 2 + 3 = 444 3) 17 - 292, 17 x 2 + 3 = 293 4) 13 - 174, 13 x 13 + 3 = 172 Thus, 13 - 174 is the odd one. |
