Question

Albert buys 4 horses and 9 cows for Rs. 13,400. If he sells the horses at 10% profit and the cows at 20% profit, then he earns a total profit of Rs. 1880. The cost of a horse is:

• A. Rs. 1000
• B. Rs. 2000
• C. Rs. 2500
• D. Rs. 3000
• E. Rs. 3500

Answer 1

The correct option is B

Rs. 2000

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

$⟹$$\frac{2}{5}x+\frac{9}{5}y=1880\Rightarrow 2x+9y=9400$.....(ii)

Solving (i) and (ii), we get : x = 2000 and y = 600.

$\therefore$ Cost price of each horse = Rs. 2000.
