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

Percentage Distribution of Total Expenditure of a Company


5.
The expenditure on the interest on loans is by what percent more than the expenditure on transport?
5%
10%
20%
40%
Answer: Option
Explanation:

Let the total amount of expenditures be Rs. x.

Then, the expenditure on interest on loans = Rs. (17.5% of x) = Rs. ( 17.5 x )
100

and the expenditure on transport = Rs. (12.5% of x) = Rs. ( 12.5 x ) .
100

Therefore Difference between the two expenditures
= Rs. ( 17.5x - 12.5x )
100 100
= Rs. ( 5x )
100

and so, the required percentage = ( 5x/100 x 100 ) % = 40%.
12.5x/100

For what reason we have to use this formula i.e. (a-b/b)?

In simple way Change/Expenditure percentage*100.

= 17.5-12.5/12.5*100 = 40%.

Formula: a-b/b;

a = (17.5x/100); b = (12.5x/100).
a-b = (5x/100);

So, (a-b/b) = ((5x/100) by 12.5x/100).

Can anybody tell me that why in the 6th line of solution they have divided 5x/100 by 12.5x/100 and not 5x/100 by 17.5x/100?
