Question 988016
<pre>
Let the price of 1 goat be rs x.
Then the price of 1 sheep is 2x rs.

the average price of 12 goats and 12 sheeps is rs 600

So  12x + 12(2x) = 600
       12x + 24x = 600
             36x = 600
               x = {{{600/36}}}
               x = {{{50/3}}} rs  

So the average price of a goat is {{{50/3}}} rs

And the average price of a sheep is 2 times {{{50/3}}} rs. which
is {{{100/3}}} rs.

Therefore 3 goats sell for 3 times {{{50/3}}} or 50 rs
Therefore 2 sheep sell for 2 times {{{100/3}}} or {{{200/3}}} rs.

{{{50+200/3=150/3+200/3=350/3=116&2/3}}} rs.
