The following line graph shows revenue and expenditure of company A for 5 years (in Lakhs):

What is the average expenditure of the company A over the years?

If the efficiency of Q increases by $$ {33{1\over 3}{\%}}$$ and P and Q start to work together, while at the same time R starts destroying the work. Find in how many days work will be completed.

A alone can complete a work in 25 days and B alone can do the same work in 20 days. A started the work and after working 7 days B joined A to finish the remaining work. In how many days, the total work will be finished?
