How many people are standing in the queue at the counter? I. If four more people join the queue, the number in the queue will be more than 15 II. More than 10 people are standing in the queue III. There are more men than women in the queue IV. If three people give up and leave the queue, the number remaining will be less than 10 V. Less than 20 people are standing in the queue Which two statements are sufficient to answer the question?
Correct answer: D. I & IV
- A. I & III
- B. II & III
- C. II & V
- D. I & IV
Explanation
Option D provides the sufficient information to find out the number of people standing in a queue i.e It states that if 4 more people join the queue the number of people in queue would be greater than 15, considering the number of people in queue=x gives an idea that 11≤ x ≤ 15 Whereas IV states that if three people leave the queue the value of c would be less than 10 i.e 12≥x ≥10, Giving an idea that x= 11 or 12 as both the statements resonates with these two numbers and together gives sufficient information. All the other options do not give sufficient information together as they do not relate with each other.
