Answer 2

Answer:800 rs.

Step-by-step explanation:

LET the price of horse =x

so 10% profit on horse =0.1x

profit on 4 horse =0.4x

let price of cow = y

then 20% profit = 0.2y

profit on 9 cows =1.8y

As given

4x+9y = 1340

and

0.4x+1.8y =188

Or 4x+18y =1880

By substracting 1 from 2

9y = 540

Y=60

And x=200

SO price of horse is 200rs. and cow is 60 rs.

so he paid for 4 horses = 4*200 = 800rs.
