Road quiz

Are you tired of reading useless gibberish? Let me give you some interesting post today. A quiz. And a mathematical quiz!! I have always been a big fan of mathematical quizzes. Because they make me feel smart!

Here is the quiz

A travels everyday from her (or his) home to office in two wheeler. The distance is around 18 km. The speed in which she goes depends on the circumstances. In a clear stretch, she goes at 50 kmph, if there lot of traffic, she goes at 30 kmph and near traffic signals she goes or she is forced to go at around 2kmph. Some times to avoid pot holes, she has to go at 10 kmph. And at each traffic signal she has to wait for almost 10 minutes.

Now if there are 15 traffic signals she has to cross, and there are 300 pot holes large and small, and three roads which have heavy traffic, what is the time required for her to travel the distance?

Now for those hungry for more complexities, here are additional problems.

If A is a he instead of she, whenever his vehicle touches others' vehicle or vice-verse , he spends 15 minutes for verbal fight with the other traveller. But his average speed in clear stretch or otherwise is 60 kmph, except for traffic signals.

If A has a not very kind boss/organization where they cut half a day's salary if A is 10 minutes late to office, what are the number of days, he receives full day's pay? If A (is a he and) blames his wife for not preparing the breakfast early and hence causing the pay cut, what are the number of days where there is early morning fight in A's home?

Bharatha - 2. UrdhvaRoma

I wanted to write about Karna as my part 2 of Bharatha because he is the real tragic hero of MahaBharatha. But net is filled with writings about him. So let me write about little known son of Arjuna called Urdhvaroma. And I don't want to write as twisted tale but as I have heard it from my Yankatte (atte - aunt). Yankatte was my mother's aunt and she was widowed in childhood. She would spend some time in my granny's house and some time in her husband's house. She would tell us all beautiful stories. UrdhvaRoma was a son of Arjuna (I think. Or may be Bhima's son. I don't remember clearly. ) He was living in the forest. One day when he was practicing archery, Arjuna and Krishna were passing by. Krishna indicated Arjuna to hide and watch. This boy shot an arrow to a large tree. And all the leaves of the tree fell down except for 5 and a half leaves. Krishna and Arjuna came forward and asked him what was all this about. The boy told " After few years there wi
