- D. 13 : 14 Discuss
Correct Answer: 10 : 13
Explanation:
Let expenditures of Company B in 2003 and 2004 are Rs. 5x and Rs. 7x respectively; then
their income in 2003, I1= 5x + 40/100 x 5x = Rs. 7x
Also their income in 204, I2 = 7x + 30/100 x 7x = Rs. 91x/10
Hence, the required ratio = 7x : 91x/10 = 10 : 13

- C. 121.5
- D. 130.5 Discuss
Correct Answer: 962/3
Explanation:
Let expenditure of company B in 2005 = Rs. x; then
I1(Income) = x + 35/100 x = Rs. 27x/20
Since . expenditure of company B in 2006 = 90/100 x Rs. x = Rs. 9x/10.then
I2(Income ) = 9x/10 + 45/100 x 9x/10 = 9x/10 +81x/200 = Rs. 261x/200
Hence, required percentage = 261x/200/27x20 x 100 = 290/3 = 962/3%
- 4. If the income of A in 2005 was Rs. 1,42,500 what was its expenditure in that year?

- B. Rs. 95500
- C. Rs. 99,500
- D. Rs. 1,05,000 Discuss
Correct Answer: Rs. 95000
Explanation:
Expenditure = Income - Profit
As per given graph in question,
Income in 2005 = 1,42,500 Rs.
Profit in 2005 = 50%
Let expenditure of Company A in 2005 = Rs. E; then
E + E x 50/ 100 =142500
? E + E x 1/2 =142500
? (2E + E)/2 =142500
? 3E =142500 x 2
? E =142500 x 2/ 3
? E = 47500 x 2
? E = Rs. 95000
- 5. If the experditure of company 'A' in 2004 was Rs. 75 lakhs and income of Company A in 2004 was equal to its experditure in 2005. What was the total income (in lakhs Rs) of the company A in 2004 and 2005 together?
