Out of 13 cows, one worth RS 625 was removed and a horse was included.
If the average price of the animal increased by RS 15,
find the price of the horse?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Your equation is

%28C%5B12%5D+%2B+625%29%2F13 - %28C%5B12%5D%2Bx%29%2F13 = -15,

where C%5B12%5D is the cost of the remaining 12 cows.


Multiply by 13 both sides, cancel C%5B12%5D and then find x.
