Four clusters have been given out of which three are alike in some manner and one is different. Select the one that is different.

Option

The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs, EXCEPT one. Find that odd number pair.

Four clusters have been given out of which three are alike in some manner and one is different. Select the one that is different.

Option

Select the odd word/letters/number/number pair from the given alternatives.

Options:

In each of the following questions, certain pairs of words are given, out of which the words in all pairs except one, bear a certain common relationship. Choose the pair in which the words are differently related?

Study the given pattern carefully and select the number that can replace the question mark (?) in it.
 First row: 3, 2, 30
 Second row: 7, 5, 175
 Third row: 4, 6, ?
 (NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. For example, 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.)

Three of the following four letter-clusters are alike in a certain way and one is different. Pick the odd one out.

The second number in the given number-pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number-pairs EXCEPT one. Find that odd number-pair.
