1. 4 2. 5 3. 6 4. 7
Ans: Total number of legs of both 7 & 8 leged octobus = 54. Find number of 7 leged octopuses
Go from answer
4(7 leged octobus) + X = 54.
5(7 leged octobus) + X = 54. Similarly do for all. The x you get should be exactly divisible by 8. Only one answer will satisfy the condition.
Note: You may find lot of nonsense stuff to test verbal ability. Just take required data alone. From the next question onwards I post necessary data only.
