Direction: Study the following graph carefully and answer the questions given below.

  1. If the total income in 1992 for Company B was 140 crores, what was the total expenditure in that year?
    1. 100 billion
    2. 110 billion
    3. 98 billion
    4. Data inadequate
    5. None of these
Correct Option: E

As per given question,
Total income of company B in year 1992 = 140 crore
Given in the graph that the % Profit of company B in year 1992 = 45 %
Let us assume that the total Expenditure of company B in year 1992 = E
Use the below formula to calculate

% Profit =
Income - Expenditure
x 100
Expenditure

or, 45 =
140 - E
x 100
E

⇒ 45E = 140 x 100 - 100E
⇒ 45E = 14000 - 100E
⇒ 45E + 100E = 14000
⇒ 145E = 14000
⇒ E = 14000/145 = 2800/29 = 96.6 million $
