Quiz Begins Here

Q #1
⏰ :

Directions: Read the following information to answer the question.

If two positive numbers a and b are such that a <50 and b >25, then which of the following can never be true?

  1. b > a
  2. 2a – b < 0
  3. III.    3a + 2b > 200

Discuss

Statement I: Since a can take any value including those less than 25, this statement can be true.

Statement II: By observation, we can make out that 2a-b can be less than zero. 

Statement III : 3a + 2b

=3(50-k) + 2 (25+l) = 200 – 3k + 2l

This can be grater than 200 since there is no restriction on the value if I where as k<50.

Q #3
⏰ :

Directions: Read the following information to answer the question.

Two baskets containing Bananas and Apples respectively are placed adjacent to each other. A man picks up a certain number of Bananas and half that number of Apples from the respective baskets and transfers them to the other basket. If the Banana basket does not have any Bananas left after 20 such operations but has 100 apples in it while the Apples basket has twice the number of Apples as Bananas in it, then find the total number of Apples in both the basket put together.

If he puts x bananas in, he takes out x/2 apples i.e., 100 apples are remaining means 200 bananas were there initially. Therefore the apples basket has 400 apples and local number of apples = 100 + 400 = 500
