Answer 2

Answer:

15 horses

Step-by-step explanation:

let the no. of horses is n and cost of each horse is x

so n*x= 3000 --------1

as three horses died and rest are sell 65 rs more than cost price. so

$(n-3)(x+65)= 3000*\frac{106}{100}\\\\nx+65n-195-3x=3180\\\\3000-195+65n-3x=3180\\\\65n-3x=375\\\\65n-3*\frac{3000}{n}=375\\\\65n^{2}-375n-9000=0\\\\13n^{2}-75n-1800=0$

by solving this we get n=15

so there were total 15 horses he bought.
