When length of a rectangle was increased by 20 and breadth remains constant then area was increased ...........

Quantitative Aptitude (SBI-CL) Data Sufficiency

When length of a rectangle was increased by 20% and breadth remains constant then area was increased by 100 sq. cm. What is the perimeter of the rectangle?

Statement I : After increasing the length, the rectangle becomes a square.

Statement II : After increasing the length, all the angles of the rectangle becomes 90 degree.

The data in statements I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.

The data in statements II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question.

Either Statement I or Statement II alone is sufficient to answer the question.

Neither statement I nor statement II is sufficient to answer the questions.

The data in both the statements I and II together is necessary to answer the question.

Explanation:

Once we get the value of a, we can conclude the length and breadth and can get perimeter
From the Statement II, we could not conclude either new figure becomes rectangle or square because
even in rectangle all angles are 90 degree.
Therefore, the data in statements I alone is sufficient to answer the question, while the data in
statement II alone is not sufficient to answer the question.
Hence, option A is correct.
