Answer provided by our tutors

Let x be the cost of one goat, y be cost of one cow.

25x + 3y = 75000

33x + 2y = 69600

ð  50x + 6y = 150000 and 99x + 6y = 208800

ð  49x = 58800

ð  X = 1200, y = 15000

Total amount after selling = 25*1.5*x + 3*1.4*y = 4.2y + 37.5x = 42*1500 + 375*120 = 63000 + 45000 = 10800
