Solution(By Examveda Team)

In the given Question Tinu beats Minu by 100m.
Therefore Minu run 1400m when Tine run 1500m
Ratio of Tinu and Minu Speed is 1500:1400 = 15:14
Similarly Ratio of the Speed of Minu and Rinu is 1500:1200 = 5:4

Therefore Ratio of speed of Tinu and Rinu is 15/14 * 5/4 = 75:56
when Tinu run 1500m then Rinu Run = ( 56/75 ) * 1500 = 1220m
Therefore Tinu beat Rinu by 1500 - 1220 = 380m
