Asked by Indiana Jones

There are 648 cows and sheep on a farm. The ratio of the number of cows to the number of sheep is 5:4. At an auction, 2/3 of the sheep and some cows are sold. The ratio of the number of cows to the number of sheep left is no 3:1. How many cows are sold?
Is the answer 144?

Nope. Too bad you didn't show your work...
c+s = 648
c/s = 5/4
If x cows are sold then
(c-x)/(s/3) = 3/1
Answered by henry2,
X sheep.
5x/4 cows.

x + 5x/4 = 648,
4x + 5x = 2592,
X = 288.
5x/4 = 360.
After the auction:
288/3 = 96 sheep left.
Cows left = 3 * 96 =

Answered by henry2,
Cows sold = 360 - cows left.
