The rate of work of A and B is in the ratio 2 : 3. What will be the ratio of the days taken by them to complete the work?

A man bought three articles, each of which cost Rs 3000. He sold those articles at 10% profit, 5% profit and 15% loss respectively. What is the total profit/loss percentage earned by him?

A can do 50% of a work in 16 days, B can do 1/4 of the same work in 24 days. In how many days will they complete 3/4th of the work working together?

Divide 50 into two parts so that the sum of their reciprocals is   $${1\over 12} $$
