**1. Answer : 3**

**Explanation : **Expenditure of Company B = 60 lakh

Income of Company B = $60\times \frac{180}{100}$= 108 lakh = 1 crore 8 lakh

Income of Company A = $10800000\times \frac{4}{5}$ = Rs. 8640000

Therefore, Required differeence = 10800000 - 8640000 = Rs.2160000

**2. Answer : 1**

**Explanation : ** Total expenditure on the employees of company A = $5000000\times \frac{28}{100}$ = Rs.1400000

Average Salary of the employees = $\frac{1400000}{100}$ = Rs.14000

**3. Answer : 1**

**Explanation : **Tax paid by Company A : Tax paid by Company B

= $5000000\times \frac{14}{100}$: $6000000\times \frac{6}{100}$

= 700000 : 3600000 = 35 : 18

**4. Answer : 2**

**Explanation : **Difference = $6000000\times \frac{34}{100}-5000000\times \frac{28}{100}$

= 2040000 - 1400000 = Rs.640000

**5. Answer : 5**

**Explanation : **Expenditure on Machine and Electricity of Company B = $6000000\times \frac{18}{100}$ = Rs.1080000 = 10.8 lakh

Expenditure on Machine and Electricity of Company A = $5000000\times \frac{12}{100}$ = Rs.600000 = 6 lakh

Therefore, Required % = $\frac{1080000-600000}{600000}\times 100$ % = $\frac{48}{60}\times 100$% = 80%

Hence expenditure of Company B is 80% more than Company A.
