Answers.
A) Rs.2007	B) Rs.2000	C) Rs.2089	D) Rs.2067	E) Rs.2098
Let C.P. of each horse be Rs. x and C.P. of each cow be Rs. y.   Then, 4x + 9y = 13400 -- (i)   And, 10% of 4x + 20% of 9y = 1880   2/5 x + 9/5 y = 1880 =&gt; 2x + 9y = 9400 -- (ii)   Solving (i) and (ii), we get : x = 2000 and y = 600.   Cost price of each horse = Rs.2000.   Answer:Rs.2000
