Question

Ms. Macy asks her students the following question:
"The sum of two numbers is five times the product of 24 and 2. If the first number is 15, find the second number."

Help her students find the correct answer from the options given below.

• A. 225
• B. 210
• C. 230
• D. 215

Answer 1

The correct option is A 225

Let the unknown number be x.

We know that the first number is 15.

It is given that sum of the above two numbers is five times the product of 24 and 2.

$x+15=5\times (24\times 2)$

$\Rightarrow x+15=5\times 48$
$\Rightarrow x+15=240$
$\Rightarrow x=240-15$

Thus,
$\Rightarrow x=225$

Hence, the second number is 225.
