A. 0.50

B. 1.00

C. 1.50

D. 2.00

A. Guaranteed increase in dissolved oxygen

B. Elimination of disease risk

C. Reduced competition for feed

D. Automatic improvement in water quality

B. Crop finance primarily meets seasonal cultivation expenses and is repaid from crop-cycle income

C. Crop finance cannot be linked to actual crop production

D. Crop finance is always secured only by residential property

E. Crop finance is intended exclusively for purchasing tractors

A. ₹1 lakh

B. ₹2 lakh

C. ₹3 lakh

D. ₹5 lakh

QUICK CALCULATION CHECK

Q15. Feed Conversion Ratio

FCR = Feed consumed ÷ Weight gain

= 4,000 ÷ 2,000

= 2.00

Q19. Operating Surplus

Annual gross income − Annual operating costs

= ₹8 lakh − ₹5 lakh

= ₹3 lakh
