Mahesh has certain number of problems with him. He can solve some fixed number of problems every hour. After solving for 5 hours, he is left with 384 problems. If he had solved for 10 hours, he is left with 144 problems to solve. Find the number of problems with Mahesh initially.

The probability that A can solve a problem is 2/3 and that B can solve it is 3/4.If both attempt the problem, what is the probability that the problem gets solved ?

A can solve 75% of the problems in a book on mathematics and B can solve 70%. What is the probability that a problem chosen at random is solved?

The probability that A can solve a problem is 4/5 and B can solve it is 2/3 .If both attempt the problem what is the probability that exactly one of the problem gets solved ?

The odds against A solving a problem are 8 to 6 and the odds in favour of B solving the same problem are 14 to 10. Then the probability that the problem will be solved if both of them try the problem is
