The development budget of a district council includes expenditure on feeder roads, schools and water supply. The expenditure on feeder roads, schools and water supply are in the ratio 7:15:2. The expenditure on roads is 28,000.

Find the expenditure on water supply?

Express the expenditure on water supply as a percentage of the
total budget for these three projects?

Answer 1

$\fontsize{18}{10}{\textup{\textbf{The expediture is 8000 and 8.33 percent of total }}}$

Step-by-step explanation:

Let the expenditure on feeder roads, schools and water supply be

7x,15x and 2x

Expenditure on roads=28000=7x

=>x=4000

So, expenditure on water supply=2x=2*4000

=8000

Expenditure of water supply as percentage of total= 2x*100/(7x+15x+2x)

=200/24=100/12

=8.33%
