Let’s assume that the man and the train normally met at the crossing at 8 A.M., then the usual time of the cyclist at the bend is 8 A.M. and he is 6 miles behind at 7.30 A.M. But when the cyclist is late, he arrives at the bend at 8.25 A.M. and therefore he is six miles behind at 7.55 A.M. Since the train takes 5 minutes to travel the six-mile run, the speed of the train is 72 m.p.h.

If the sari cost Rs. 100 and the blouse Rs. 10 the difference would be Rs. 90, and therefore the sari must cost more and the blouse less. A little thought indicates the sari costs Rs. 105 and the blouse Rs. 5. So the difference in cost is Rs. 100.
