Two people start from opposite ends A and B of a corridor and move towards B and A respectively. When they meet for the first time, the respective distances covered by them is in the ratio 3 : 5 and one of them has covered 30 metres more than the other. If the speed of the person from A is 6 m/s, when will the person from B reach the end A after meeting with person from A?

Correct Option - 3
Detailed Solution:The distances covered by them are in the ratio 3:5 and difference is 30 m. This means 5x – 3x = 30 or 2x = 30 or x = 15 m
Therefore, the total distance covered is equal to 120 m. Their speeds are also in the ratio 3 : 5. Since the speed of the first person is 6 m/s, the speed of the second person will be 10 m/s and he has to cover a distance of 45 m.
