Question

A number is 12 more than the other. Find the numbers if their sum is 48.

• A. $12$ and $30$
• B. $30$ and $18$
• C. $12$ and $26$
• D. $30$ and $14$

Answer 1

The correct option is B $30$ and $18$

Let the number be x and y
$\therefore x=12+y$ ----- (1)
$x+y=48$ ----- (2)
From equation (1) $x=12+y$, substitute the value in equation (2)
$12+y=48$
$12+2y=48$
$y=18$
Put the value of y in equation (1)
$x=12+18$
$x=30$
Therefore number are 30 and 18
