A rabbit farm keeps two breeds. Breed A gains \(30\) g day⁻¹ and has a feed conversion ratio (FCR) of \(3.5\) kg feed kg⁻¹ gain. Breed B gains \(45\) g day⁻¹ with an FCR of \(4.2\). The farm has \(200\) kg of feed available each day. (i) Determine the maximum number of rabbits of each breed that could be reared alone without exceeding the daily feed supply. (ii) Assuming the farmer wants to maximise total daily weight gain, find the optimal mix of the two breeds and the resulting total daily gain (in kg).

Answer Options

Correct Answer A. Maximum if only Breed A: 1 904 rabbits; maximum if only Breed B: 1 058 rabbits. Optimal mix: 1 904 Breed A rabbits and 0 Breed B rabbits, giving a total daily weight gain of 57.12 kg.
B. Maximum if only Breed A: 1 904 rabbits; maximum if only Breed B: 1 058 rabbits. Optimal mix: 1 000 Breed A rabbits and 500 Breed B rabbits, giving a total daily weight gain of 52.50 kg.
C. Maximum if only Breed A: 1 800 rabbits; maximum if only Breed B: 1 200 rabbits. Optimal mix: 1 200 Breed B rabbits and 0 Breed A rabbits, giving a total daily weight gain of 54.00 kg.
D. Maximum if only Breed A: 2 000 rabbits; maximum if only Breed B: 950 rabbits. Optimal mix: 1 500 Breed A rabbits and 300 Breed B rabbits, giving a total daily weight gain of 60.45 kg.
Correct Answer
A
Correct Option:
Maximum if only Breed A: 1 904 rabbits; maximum if only Breed B: 1 058 rabbits. Optimal mix: 1 904 Breed A rabbits and 0 Breed B rabbits, giving a total daily weight gain of 57.12 kg.
