A person sold a horse for rs 120 more than its cost and made a profit equal to 2 7 of its cost find the cost of the horse?

Let the cost of the horse be x. The person sold the horse for x + 120 and made a profit of 2/7x. According to the question, the profit made is equal to 2/7 of the cost, so we have the equation (x + 120) - x = 2/7x. Simplifying this equation, we get 120 = 2/7x. Multiplying both sides by 7/2, we find x = 420. Therefore, the cost of the horse is Rs. 420.
