4. Either I or II is sufficient
5. Neither I nor II is sufficient 

Answer 1

Correct Answer - Option 3 : Both are required 

Statement I: Colonel age is equal to the sum of cadet and general ages. Major’s age is 62yr.

Rank	Age
General
Colonel
Major	62
Cadet

 

Clearly, we do not know the age of General and cadet.

Hence, statement I is not sufficient.

Statement II: The person who is colonel is 8 year greater than major’s age.

Rank	Age
General
Colonel	70
Major	62
Cadet

 

Clearly, we do not know the age of General and cadet.

Hence, statement II is not sufficient.

Combining I and II, we get

Rank	Age
General
Colonel	70
Major	62
Cadet

 

From the statement I the sum of the general and cadet is equal to age of colonel i.e. 70 year.

Hence, both statement I and II are sufficient.
