in a certain computer programming language, variable types 'whole numbers' is defined for whole numbers from 0-255, both included, internally each number is converted into a 8 digit code in binary system(base 2), with one or more digits on left being zero, if required. operation 'inverting' converts 0 and 1 in the code in the binary system 1 and 0 respectively. what is the probability that a whole number is converted into odd whole number which is greater than itself after inverting? @scrabbler pehle yeh question kehna kya chaha raha woh samjha do 😛

A & B working alone can do a piece of work in 40 days & 120 days respectively.A & B start working together on that work but after having worked for 10 days, additional work came in. The additional work is such that B would take 40 days working alone to complete it.In order to cope with the additional work, C is inducted and the remaining work is finished in 5 days .
Find the no. of days that C alone would take to complete the original work ??
a boy goes to his girlfrnd's college to pick up her daily. they together start from college exactly at 3:30 towards home. on a particular day, girl leaves college earlier at 2:30 pm at a speed of 6 kmph for home and met to the boy somewhere between college and home, and from that meeting point they immediatley returned back towards home. and thus they reach home 24 minute earlier than their routine time (ie they save 24 min.). then find out speed of boy.
pls explain approach.......
