# % Profit = [(Income –Expenditure)/ Expenditure]*100.

2.1 ) If the expenditure of company B in 2008 was Rs.200 crores. What was the income?

1. 240 Crores
2. 220 Crores
3. 160 Crores
4. Cannot be determined
5. None of these.

Solution:Let the income be Rs. X Crores.

20 = [(x-200)/200] × 100

• 40 = x-200
• X=Rs. 240 crores.

2.2) If the income of Company A in 2010 was Rs.600 crores, what was its expenditure?

1. 360 crores.
2. 480 Crores.
3. 375 Crores.
4. Cannot be determined
5. None of these

Solution: The income of Company A in 2002 is Rs. 600 crores and % profit = 60
Assume expenditure is x.
60 = [(600 – x)/x] ×100
x= [(600 – x)/ 60 ] × 100
3x = 3000 – 5x
8x = 3000
X = Rs. 375 Crores

2.3) If the income of company B in 2006 was Rs.200 crores. What was its profit in 2007?

1. 21.5 Crores
2. 153 Crores
3. 46.15 Crores
4. Cannot be determined (income and expenditure not given in 2007)
5. None of these.

Solution: 4

2.4) If the income of the two companies in 2006 were equal, what was the ratio of their expenditure?

1. 1: 2
2. 26: 27
3. 100:67
4. Can’t solve
5. None of these.

Solution: Company A, 35 = [(I – Exp1)/Exp1 ] × 100   -> (1)

35Exp1 = 100 I – 100 Exp1

135 Exp1 = 100 I

Company B, 30 = [(I – Exp2)/Exp2 ] × 100

130 Exp2 = 100 I  -> (2)
From (1) and (2)
135 Exp1 = 130 Exp2
Exp1/Exp2 = 130/135
Ratio of Expenditures of A and B ,
Exp1: Exp2 = 130 : 135
26: 27.

2.5) What is the percent increase in percent profit for company B from the year 2008 to 2009?

1. 75
2. 175
3. 86
4. Cannot be determined

Solution:= [(35- 20)/ 20 ] × 100  = 75
