Q1. In the given question, choose the number-letter group which is different from the others.

A PH3 Correct

B XL2

C JB5

D OE3

Explanation

Use the alphabetical positions of the two letters. In XL2, X is 24 and L is 12, and 24 divided by 12 gives 2. In JB5, J is 10 and B is 2, and 10 divided by 2 gives 5. In OE3, O is 15 and E is 5, and 15 divided by 5 gives 3. In PH3, P is 16 and H is 8, so the quotient is 2, not 3. Therefore, PH3 is the different group.
