Quantitative Aptitude(IBPS CL) Data Sufficiency Add to Study Deck

Directions: Each question below is followed by two statements I and II. You have to determine whether the data given in the statement is sufficient for answering the question.
You should use the data and your knowledge of Mathematics to choose the best possible answer.

i. Sum of inverse of a and b is equals to 6/5
ii. Multiplication ‘a’ and ‘b’ is equals to 5

The data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question

The data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.

The data either in Statement I or in Statement II alone are sufficient to answer the question.

The data in both Statements I and II together are necessary to answer the question.

The data even in both Statements I and II together are not sufficient to answer the question.

Explanation:

Here, we have 2 unknowns and one equation
So, statement I alone is not sufficient to answer the question a x b = 5
Here, we have 2 unknowns and one equation
So, statement II alone is not sufficient to answer the question
On combining both the statements
So, now we have two equations and two unknowns
So, option (d) is the correct answer.
