Common Information Question: 1/5

The total amount of expenditures of the company is how many times of expenditure on research and development?









 Hide Ans

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:

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

It can easily be adding all i.e 100 and dividing it by 5=20
