Q1:

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

ANS:B - 20

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.
