Two numbers are in the ratio 2 : 3. If their L.C.M. is 48. what is sum of the numbers?A. 28 B. 40C. 64 D. 42

To solve this problem, we need to understand that the LCM (Least Common Multiple) of two numbers in a ratio is equal to the product of the ratio and the highest number in the ratio.

Step 1: We know that the ratio of the two numbers is 2:3. This means that we can represent the numbers as 2x and 3x, where x is a common multiplier.

Step 2: We know that the LCM of the two numbers is 48. Therefore, we can set up the equation 2x * 3x = 48.

Step 3: Simplifying the equation gives 6x^2 = 48.

Step 4: Solving for x, we get x^2 = 48/6 = 8, so x = sqrt(8) = 2.83 (rounded to two decimal places).

Step 5: Now that we know x, we can find the two numbers. The first number is 2x = 22.83 = 5.66 (rounded to two decimal places) and the second number is 3x = 32.83 = 8.49 (rounded to two decimal places).

Step 6: The sum of the two numbers is 5.66 + 8.49 = 14.15 (rounded to two decimal places).

So, the sum of the two numbers is approximately 14.15. However, this is not an option in the multiple choice answers provided. It seems there may be a mistake in the problem or the answer choices.
