Question : Directions: Arrange the following words as per their order in the dictionary.
1. Physical 2. Physics 3. Physiology 4. Physician 5. Phone

Option 1: 5, 1, 4, 2, 3

Option 2: 5, 1, 2, 3, 4

Option 3: 1, 4, 5, 2, 3

Option 4: 1, 5, 4, 3, 2

Correct Answer: 5, 1, 4, 2, 3

Solution : Given:
1. Physical 2. Physics 3. Physiology 4. Physician 5. Phone

Step 1: Compare the first and second letters of each word. Since all the words started with the same letters P and h , move on to the next letter.
Step 2: The third letter of each word is either o or y . Based on the alphabetical order of these letters, we can arrange them – Ph o ne, Ph y sical, Ph y sics, Ph y siology, Ph y sician.
Step 3: Compare the sixth letter of (Physi c al, Physi c s, Physi o logy, Physi c ian). Physical, Physics, and Physician will come before Physiology in the sequence as c comes before o in the alphabetical system.
Step 4: Compare the seventh letter of (Physic a l, Physic s , Physic i an). Physical will come before Physics and Physician as a comes before s and i in the alphabetical system. Similarly, Physician will come before Physics as i comes before s .

So, the sequence is Phone, Physical, Physician, Physics, Physiology, or 5, 1, 4, 2, 3. Hence, the first option is correct.
