# Percentage profit earned by two companies over the given years.

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

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

- 240 Crores
- 220 Crores
- 160 Crores
- Cannot be determined
- 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?**

- 360 crores.
- 480 Crores.
- 375 Crores.
- Cannot be determined
- 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?**

- 21.5 Crores
- 153 Crores
- 46.15 Crores
- Cannot be determined (income and expenditure not given in 2007)
- 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: 2
- 26: 27
- 100:67
- Can’t solve
- 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?**

- 75
- 175
- 86
- Cannot be determined

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