Ans is 60 km/h
speed of train relative to man: 110/6 * 18/5 km/hr
= 66 km/hr
let speed of train= x
therefore x+6 = 66
x= 66-6
x=60 km/hr Ans

answer is b) 60 kmph
solution is:-
speed of train relative to man i,e. combined speed of train and man=110/6 * 18/5=66 kmph
let speed of train individually= x kmph
and speed of man individually= 6kmph
so. x+6=66
so, x=60 kmph


or in other way,
combined speed of train and man=110/6 * 18/5=66 kmph
speed of man=6 kmph
therefore, speed of train=66-6=60 kmph
