Question . 88
After what time will the two persons, Tez and Gati, meet while moving around the circular track? Both of them start from the same point and at the same time
I. Tez moves at a constant speed of 5 m/s, while Gati starts at a speed of 2 m/s and increases his speed by 0.5 m/s at the end of every second thereafter.
II. Gati can complete one entire lap in exactly 10 seconds
Explanatory Answer
Method of solving this CAT DILR Question from Data Sufficiency question
(d) From the two statements we can obtain a relation between the times taken by Tez and Gati to complete one lap. But, we do not know the direction in which they are moving they would require less time if they are moving in opposites direction then they when moving in the some direction.
∴ Even both the statement together are not sufficient to answer the question.
