Common Information

The bar graph given below shows the percentage distribution of the total expenditures of a company under various expense heads during 2003.

 Q. Common Information Question: 1/5 The total amount of expenditures of the company is how many times of expenditure on research and development?
 ✖ A. 27 ✔ B. 20 ✖ C. 18 ✖ D. 8

Solution:
Option(B) is correct

Let the total expenditures be Rs. $x$.

Then, the expenditure on Research and Development (R & D):
= Rs. (5% of x)
= Rs.$\left(\dfrac{5}{100}\right)×x$
= Rs.$\dfrac{x}{20}$

Ratio of the total expenditure to the expenditure on R & D:
$=\left[\dfrac{x}{(x/20)}\right]$
$=\dfrac{20}{1}$

Then, the total expenditure is 20 times the expenditure of Research and Development
