Answer / ashish madhavi
Hey buddies no need for any type of calculation this
problem can b solved orally
METHOD:
to any type of an problem on WORK
first collect the numbers in the question and find the
common multiple
for eg in our above question (4,6) common multiple = 12
so suppose there are 12 files to b completed
A alone can do the work in 6 days
therefore /day A completes 2 files
A & B together completes the work in 4 days
therefore /day they complete 3 files
therefore as A completes 2 files /day B completes 1 file/day
so B alone requires 12 days to complete the work (1 file
each day)

Q2) Paul the octopus who has been forecasting the outcome of FIFA world cup matches with tremendous accuracy has now been invited to predict ICC world cup matches in 2011. We will assume that the world cup contenders have been divided into 2 groups of 9 teams each. Each team in a group plays the other teams in the group. The top two teams from each group enter the semi finals ( after which the winner is decided by knockout). However, Paul has a soft spot for India and when India plays any team, Paul always backs India. Alas, his predictions on matches involving India are right only 2 out of 3 times. In order to qualify for the semi finals, it is sufficient for India to win 7 of its group matches. What is the probability that India will win the ICC world cup
