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

Solution : Given:
1. Weather 2. Weasand 3. Wealth 4. Weapon 5. Weekend

Step 1: Since all the words start with the same letter W , so move on to the next letter.
Step 2: The second letter of each word is the same, i.e., e . So, move on to the next letter.
Step 3: The third letter of each word is either e or a . The arrangement can be – (Weather, Weasand, Wealth, Weapon), and Weekend.
Step 4: Compare the fourth letter of (Wea t her, Wea s and, Wea l th, Wea p on). Wealth will come before Weather, Weasand, and Weapon as l comes before t , s , and p according to the alphabetical system. Weapon will come before Weather, and Weasand as p comes before t , and s according to the alphabetical system. Similarly, Weasand will come before Weather as s comes before t according to the alphabetical system.

So, the sequence is Wealth, Weapon, Weasand, Weather, Weekend, or 3, 4, 2, 1, 5. Hence, the third option is correct.
