​

Answer 1

Answer:

12000

Step-by-step explanation:

Cost of one cow=x

And cost of one goat=y

So a/c to question

3x+8y=47200. (1)

And 8x+3y=100200 (2)

Now multiply with 8 in equation (1)and 3 with in equation (2)

24x+64y=377600. (3)

24x+9y=300600 (4)

Now subtract equation (4) from (3)

55y=77000

Y=77000÷55

Y=1400

Put the value of y in equation (1)

3x+8×1400=47200

3x+11200=47200

3x=47200-11200

3x=36000

X=12000

Hence cost of one cow =12000
