Tech Mahindra Company Numerical Ability Time Distance and Speed

Train A traveling at 60 km/hr leaves Mumbai for Delhi at 6 P.M. Train B traveling at 90 km/hr also
leaves Mumbai for Delhi at 9 P.M. Train C leaves Delhi for Mumbai at 9 P.M. If all three trains meet at
the same time between Mumbai and Delhi, what is the speed of Train C if the distance between Delhi
and Mumbai is 1260 kms?

let time taken by train b is t hrs to meet train A
so let the train A and B meets at distance x
As the distance will be same so
time taken by train A is t+3
so 60*(t+3)=90*t
so t = 6hrs
now distance covered by train A is 90*6=540
And the remaining distance will be covered by train c to meet = 1260-540=720
so speed of train c is 720/6=120km/hr

120Kmph, at the time train B starting, train A covers 180km so the train B meet train A after 6hrs.
T=[180÷(90-60)]=6hrs.
In this 6hrs the train B covered 540km and also a covers 540km. The distance remains is 1260-540=720km. So train C covers 720km in 6hrs. Then the speed of the train C is 720÷6=120kmph.

so let the train A and B meets at distance x
As the distance will be same so
time taken by train A is t+3
so 60*(t+3)=90*t
so t = 6hrs
now distance covered by train A is 90*3=540
And the remaing distance will be covered by train c to meet = 1260-540=720
so speed of train c is 720/6=120km/hr
