Question

If the ratio of the two numbers is 3: 5 and their sum is 360 find them

Answer 1

Let the common multiple of the given ratio be x.
Now,
First number = 3x
Second number = 5x
Given:
Sum of the two numbers = 360
$\therefore$ 3x + 5x = 360
= 8x = 360
= x = 45
Thus, we have:
First number = 3$\times$45 =135
Second number = 5$\times$45 = 225
