Q.A:

1.  D. Rs. 14,85,000
Income  = 585000/65 * 165 = 1485000
2. A. Rs. 23 Lakhs
Amount invested by Company A in 2014 = 2/3 * 30,00,000 = 20 lakh
Amount invested by Company B in 2014 = 1/3 * 30,00,000 = 10 lakh
Profit earned by Company A = 75/100 * 20,00,000 = 15 lakh
Profit earned by Company B = 80/100 * 10,00,000 = 8 lakh
Total Profit = 23 lakh
3. D. 34:31
Income of A in 2005 = 1.70x
Income of B in 2005 = 1.55x
A:B = 1.70x : 1.55x = 34 : 31
4. A. Rs. 9,06,250
Income of Company A in 2012 = 145/100 * 10,00,000 = 1450000
Amount invested in 2013 = 1450000 / 160 * 100 = 9,06,250
5. C. Rs. 21 lakh
55/100 * x = 11,55,000
x = 21 lakh
6. D. Rs. 13.64 Lakh
Income of Company B in 2009 = 1.55 * 16,00,000 = 24.8 lakh
Investment in 2010 = 24.8 lakh
Profit earned in 2010 = 55/100 * 24,80,000 = 13.64 lakh
7. A. 70%
Average percent profit = 495/7 = 70.71%
8. B. Rs. 4.5 Lakh

Profit earned in 2013 = 48 – 30 = 18 lakh
Profit earned in 2014 = 45/100 * 30,00,000 = 13.50 lakh
Difference = 18 – 13.5 = 4.5 lakh
9. A. Rs. 8 Lakh
Average Profit = [(90/100 * 10,00,000) + (70/100 * 10,00,000)] / 2 = 8 lakh
