Correct option is D

Solution:
Total income = Rs. 3125000
Income from others is 12% =$$\frac{12}{100}$$​× 3125000 = 375000

Income from Catla is 25% = $$\frac{25}{100}$$​ × 3125000 = 781250

Income from Prawns is 12% = $$\frac{12}{100}$$​ × 3125000 = 375000

Income from Pomfret is 6% = $$\frac{6}{100}$$​ × 3125000 = 1875000

Income from Hilsa is 45% = $$\frac{45}{100}$$​ × 3125000 = 1406250
Total profit = Rs. 600000
Profit from others is 22.5% = $$\frac{22.5}{100}$$​× 600000 = 135000
Profit from Catla is 23% =$$\frac{23}{100}$$​ × 600000 = 138000

Profit from Prawns is 23% =$$\frac{23}{100}$$​ × 600000 = 138000

Profit from Pomfret is 9.5% =$$\frac{9.5}{100}$$​ × 600000 = 57000

Profit from Hilsa is 22% = $$\frac{22}{100}$$​ × 600000 = 132000
Profit per rupee income by selling others = $$\frac{135000}{375000} = 0.36$$​​

Profit per rupee income by selling Catla = $$\frac{138000}{781250} = 0.176 \approx 0.18$$​​

Profit per rupee income by selling Prawns = $$\frac{138000}{375000} = 0.368$$​

Profit per rupee income by selling Pomfret =$$\frac{57000}{1875000} = 0.034$$​

Profit per rupee income by selling Hilsa = $$\frac{132000}{1406250} = 0.093$$​​
∴ By selling Prawns is the maximum profit per rupee of income.
