Explanation

The product of two numbers equals the product of their HCF and LCM. Therefore, 275 * x = 11 * 825. Solving for x gives x = (11 * 825) / 275 = 33.

AI explanation

Use the identity that the product of two numbers equals the product of their HCF and LCM. We set up the equation 11 times 825 = 275 times the unknown number. Multiplying gives 9075 = 275 times the unknown number. Dividing 9075 by 275 gives the other number as 33.
