Percentage Distribution of Total Expenditure of a Company


1.
The total amount of expenditures of the company is how many times of expenditure on research and development?
27
20
18
8
Answer: Option
Explanation:

Let the total expenditures be Rs. x.

Then, the expenditure on Research and Development (R & D)

    = Rs. (5% of x)

    = Rs. ( 5 x x )
100

    = Rs. ( x ) .
20

Therefore Ratio of the total expenditure to the expenditure on R & D

    = ( x )
x/20

    = ( 20 ) .
1

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

The whole expenditure is 100. Therefore, 100 is 5*20 times. Since R& D is 5%.

Let x be the total expenditure.
Let the total expenditure is t times the expenditure of R&D.
As per question, we have to find t such that x = t*(5/100)*x.
This implies x/((5/100)*x ) =t
This implies 100/5=t.
Therefore, t= 20.

@Tenzin wangdi.

Total expenditure always be 100. Right?

Alternative method= total expenditure/expenditure on R&D.

=100/5=20 ANS.
