​

Answer 1

Answer:

Rs. 8,000 ; Rs. 11,500

Step-by-step explanation:

Assume a trader bought one horse for Rs. "x", then another horse a trader bought for Rs. (19,500 - x)

If a trader sold one horse at a loss of 20% ⇒ a horse was sold for 80% of a buying price, assume it will be Rs. 0.8(19,500 - x)

If a trader sold another horse at a profit of 15% ⇒ a horse was sold for 115% of a buying price, assume it will be Rs. (1.15x).

1.15x = 0.8(19,500 - x)

1.15x + 0.8x = 15,600

1.95x = 15,600

x = 8,000

Rs. 8,000 ; Rs. 11,500
