Solution:

\table \Milk ,\Profit ,\CP ,\SP;\Cow (\per \Litre),12%,x,x+12/100 x=110;,,,⇒x=98.21;\Buffalo,20%,y, y+{20y}/100=72;,,,⇒y=60

Milk sold in one day = 4 Litre
Total cow’s milk sold in five days = 4 × 5 = 20 Litre
Total buffalo’s milk sold in five days = 5 × 5 = 25 kg
Total CP of cow’s milk = 98.21 × 20 = Rs 1,964.2
Total CP of buffalo’s milk = 60 × 25 = Rs 1,500
Total SP of cow’s milk = 110 × 20 = Rs 2,200
Total SP of buffalo’s milk = 72 × 25 = Rs 1,800
Profit = Total SP - Total CP
= (2,200 + 1,800) - (1,964.2 + 1,500)
= 4,000 - 3,464.2
= 535.8 ≈ 536
