Then x+y x+y+z = 99;; 18x+3y+0.25z= 100
Because x, y and z are positive integers and18× 6 =108 >:100, x
Let x be equal to 1, 2, 3, 4 respectively, and then bring it into the calculation, and choose y and z as one of the positive integers, which is the correct answer.
The number of roe deer, rabbits and turtledoves brought in is 3, 8 and 88 respectively.
