Answer:
150 minutes.
Explanation:
To find the time after which Ram, Shyam and Mohan will meet together we have to find the LCM ( lowest common multiple) of the three speeds.
Prime factorisation of :
- 75 : 3×5×5
- 50 : 2×5×5
- 30: 2×3×5
LCM = 5×5 ×2×3
= 150
Therefore Ram, Shyam and Mohan will meet after 150 minutes.
