Answer 1

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

nx+65n−195−3x=3180

3000−195+65n−3x=3180

65n−3x=375

65n−3∗

n

3000

=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
