    Length of train = 156 m and time taken = 30 seconds => Speed of first train = $$frac{156}{30}=5.2$$ m/s Let speed of second train (length = 156 m) = $$x$$ m/s According to ques, => $$(x+5.2)=frac{156+156}{10}$$ => $$(x+5.2)=31.2$$
    => $$x=31.2-5.2=26$$ m/s $$ herefore$$ Speed of second train = $$26 imes(frac{18}{5})=93.6$$ km/hr => Ans - (A)
