D. 45000

**Solutions:**

Let, the cost price of cow be c and that of horse be h.

Then,

c+h=200000

Selling price of Cow & Horse = 6c/5 + 9h/10

=(12c + 9h)/10

now, (12c + 9h)/10=204000

12c+9h =2040000 …..(eq 1)

12c+12h=2400000 …..(eq 2)

3h = 360000

=> h= Rs.120000

c=200000-120000

Cost of cow = Rs. 80000

Cost of Horse=Rs. 36000

**Solution:**

Cost price of all the wheat=(20*30)+(40*25)=1600

if he makes 25% profit then total selling price=1600*5/4=2000

total mixture of wheat is 60kg. one third of which is 20kg.

Now selling price of 20kg of wheat=20*26=520

so 40kg of wheat =(2000-520)/40=37
