Solution:

\table \Milk ,\Profit ,\CP ,\SP;\Cow (\per \litre),12%,x,x+{12×x}/100=55;\Buffalo,20%,y,y+{20y}/100=36

CP of cow’s milk

=x+{12x}/100=55

x=100/112×55=49.10

CP of buffalo’s milk

=y+{20y}/100=36

y=100/120×36=30

Total cow’s milk sold in five days = 8 × 5 = 40 Litre
Total buffalo’s milk sold in five days = 10 × 5 = 50 litre
Total CP of cow’s milk = 40 × 49.10 = Rs 1,964
Total CP of buffalo’s milk = 50 × 30 = Rs 1,500
Total SP of cow’s milk = 40 × 55 = Rs 2,200
Total SP of buffalo’s milk = 50 × 36 = Rs 1,800
Profit = Total SP - Total CP
= (2,200 + 1,800) - (1,964 + 1,500)
= 4,000 - 3,464 = Rs 536
