Two brothers A and B are stationed at a point P on a very long road PQ. They start playing a game with a die. The die is in form of a cube with integers 1 to 6 written on its six faces with one number on each face. Each one of them throws the die alternately and moves forward (towards point Q) by the number of steps equal to the number that appears on the top face of the die, if this number is greater than the number appeared in the previous throw by the same brother. If the number appearing on the top face of the die in a particular throw by a brother is less than the number appearing on the top face of the die in the previous throw by him, then that brother moves (6 number appearing on the top face of the die) steps backwards towards point P. If the number appearing on the top face of the die in a particular throw by a brother is same as that in the previous throw by him, then the throw is not considered and he throws the die again till a different number appears on the top face of the die. If after a throw, someone needs to take certain number of backward steps which prompts him to go even behind P, that throw is considered as cancelled. In this case he has to throw the die again. In their first throw, these brothers move forward (towards Q) by the number of steps equal to the number that appears on the top face of the die (as they do not have any previous score to compare it with). Length of steps of these brothers is always same and constant. Round n comprises nth throw of both the brothers.
Q. 5.
In a particular throw by B, the number that appeared on the top face of the die was 1 and after that throw B was 14 steps ahead of A. Find the minimum possible number of throws required such that the distance between the two brothers becomes zero. A had got 1 on the top face of the die in his last throw.
A train Left from station P to Q. 2 hours later, another train leaves from P to Q.
Both trains reach station Q at the same time. However, if first train left P for Q and the other Q for P and travel towards each other, they would meet in 1 hour 20 minutes. Find the time taken by train 1 to travel from P to Q.
