To find how much time required by Tom and Harry to meet for the second timeSince Tom and Harry run in opposite directions and they start at diametrically opposite points, they together need to cover half the circular track = 200 meters to meet for the first time.

After the first meeting point, Tom and Harry will meet again after they together complete one full go around the circular track. Therefore Tom and Harry will meet for the second time after another 400 meters.

So we need to find the time taken by Tom and Harry to complete 600(400+200) meters together.

Statement 1Ratio of speeds of Tom and Harry is 3:2. The speed of Tom and Harry can be

Speed of Tom | speed of Harry

30 mts/sec | 20 mts/sec

60 mts/sec | 40 mts/sec

90 mts/sec | 60 mts/sec

Since we don't have a definitive values for speed of Tom and Harry, we can't find a unique value for the time taken by Tom and Harry to complete 600 meters.

Statement 1 is not sufficientStatement 2Tom is 50% faster than Harry. The speed of Tom and Harry can be

Speed of Tom | speed of Harry

30 mts/sec | 20 mts/sec

60 mts/sec | 40 mts/sec

90 mts/sec | 60 mts/sec

Since we don't have a definitive values for speed of Tom and Harry, we can't find a unique value for the time taken by Tom and Harry to complete 600 meters.

Statement 2 is not sufficientStatements 1 and 2 together and independently provide the same information and we still don't have a definite values for speeds of Tom and Harry

Statements 1 and 2 together are insufficientHence

option E
