question: There is a square with side ‘a’ and one octagon is inscribed in it. What will be perimeter of octagon.
Options:
(A) 8a/3
(B) 7a/3
(C) 5a/3
(D) a/3
(E) 11a/3
answer: Stream of consciousness: Well if it's a regular octagon then it actually trisects each side of the square in which 1/3 of the lenght of the side of the square is the length of one side of the octagon. If any one has a doubt he can draw the figure and see it
Going this way lenght of a side of a octagon is a/3 and thus perimeter would be 8a/3. The answer is (A).

Options:
(A) 20
(B) 40
(C) 120
(D) 60
(E) 10
answer:
Stream of consciousness: Vowel: E O

First letter can be filled in 2 Ways ( As the question states that first letter has to be a vowel)
Fifth letter can be filled in 1 Ways ( As the question states that the last letter has to be a vowel)
Now since each letter can be used only once, and 2 letters out of 7 letters are already used in First and fourth letter
Second letter can be filled in 5 Ways
Third letter can be filled in 4 Ways
So, Total number of ways = 2 Ways x 5 Ways x 4 ways x 1 ways = 40 The answer is (B).
