A man bought a horse and a pony for Rs. 2500. He sold the pony at a profit of 15% and the horse at a profit of 25%. If his total profit was Rs. 500, what is the cost price of the horse?1). Rs. 19502). Rs. 18003). Rs. 21004). Rs. 2000

Answer»

Let the cost price of pony be RS. x

∴ Cost price of the horse = Rs. (2500 – x)

Profit on pony = 15%

GAIN = (15 × x)/100 = Rs. 3x/20

Profit on horse = 25%

∴ Profit = [(2500 – x) × 25]/100 = Rs. (2500 – x)/4

Total profit = Rs. 500

∴ 3x/20 + (2500 – x)/4 = 500

⇒ 3x + [5 × (2500 – x)] = 500 × 20

⇒ 3x + 12500 – 5x = 10000

⇒ 2x = 2500

⇒ x = 1250

∴ Cost price of the horse is = 2500 - 1250 = Rs. 1250
