Correct Answer: 5, 2, 3, 1, 4

Solution : Given:
1. Logical 2. Locket 3. Logarithm 4. Longitudinal 5. Location

Step 1: Compare the first and second letters of each word. Since all the words start with the same letter L and are followed by o , then move on to the next letter.
Step 2: The third letter of each word is either c or g . Based on the alphabetical order of these letters, we can arrange them – Lo c ation, Lo c ket, Lo g ical, Lo g arithm, Lon g itudinal.
Step 3: Compare the fourth letter of (Loc a tion, Loc k et) and the fourth letter of (Log i cal, Log a rithm, Long i tudinal). Loc a tion will come before Loc k et in the sequence as a comes before k in the alphabetical system. Similarly, Log a rithm will come before Log i cal and Long i tudinal as a comes before i .
Step 4: Compare the fifth letter of (Logi c al, Long i tudinal). Logi c al will come before Long i tudinal in the sequence as c comes before i in the alphabetical system.

So, the sequence is Location, Locket, Logarithm, Logical, Longitudinal or 5, 2, 3, 1, 4. Hence, the first option is correct.
