(A) Let the cost price of one laptop be $Rs. y$.The total cost price of $5$ laptops is $Rs. 5y$.The total cost price of $7$ computers is $Rs. (58500 - 5y)$.The total profit is given by the sum of profits from laptops and computers:$10\% 	ext{ of } 5y + 16\% 	ext{ of } (58500 - 5y) = 7110$$\frac{10}{100} 	imes 5y + \frac{16}{100} 	imes (58500 - 5y) = 7110$$0.5y + 0.16(58500 - 5y) = 7110$$0.5y + 9360 - 0.8y = 7110$$-0.3y = 7110 - 9360$$-0.3y = -2250$$y = \frac{2250}{0.3} = 7500$Therefore,the cost price of one laptop is $Rs. 7500$.
