Back to Exercise
Albert buys 4 horses and 9 cows for ₹ 13,400. If he sells the horses at 10% profit and the cows at 20% profit, then he earns a total profit of ₹ 1880. The cost of a horse is:
- A ₹ 1000
- B ₹ 2000 Correct
- C ₹ 2500
- D ₹ 3000
Correct Answer: Option B
Let C.P. of each horse be ₹ x and C.P. of each cow be ₹ y.
Then, 4x + 9y = 13400 --------- (i)
And, 10% of 4x + 20% of 9y = 1880
⇒ 2/5 x + 9/5 y = 1880 => 2x + 9y = 9400 ----- (ii)
Solving (i) and (ii), we get : x = 2000 and y = 600.
∴ Cost price of each horse = ₹ 2000.
