It was a beautiful sunny morning. The air was fresh and a mild wind was blowing against my wind screen. I was driving from Bangalore to Brindavan Gardens. It took me 1 hour and 30 minutes to complete the journey.
After lunch I returned to Bangalore. I drove for 90 rhinutes. How do you explain it ?  Choose the correct option
A) 75 min	B) 60 min	C) 90 min	D) 80 min	E) 88 min
C   90 min   Jansi went out for shopping. She had in her handbag approximately Rs. 15/- in one rupee notes and 20 p. coins. When she returned she had as many one rupee notes as she originally had and as many 20 p. coins as she originally had one rupee notes. She actually came back with about one-third of what she had started out with.   How much did she spend and exactly how much did she have with her when she started out ?   There is nothing to explain here. The driving time there and back is absolutely the same because 90 minutes and 1 hour and 30 minutes are one and the same thing.   This problem is meant for inattentive readers who may think that there is some difference between 90 minutes and 1 hour 30 minutes.
