The bar graph shows the percentage distribution of the expenditure of a company under various expense heads during 2003.

If the interest on loans amounted to ₹3.15 crores, then the total amount of expenditure on salary, taxes and infrastructure is:

9 crores

17.5% of total expenditure = 3.15 crore

1% of total expenditure  = \(\frac{3.15}{17.5}\) = 0.18 crore

Total expenditure on salary , taxes & infrastructure = ( 20% + 10% + 20% )

= 50%

= 50 × 0.18 = 9 crore
