Answer 2

In context to question asked,

We have to determine the sum of two number.

As per question,

The ratio of two number is 4 :5

So, let the number be 4x and 5x

So, LCM of 4x and 5x will be $4\times 5 \times x = 20x$

As the LCM of given number is 100

So, we will get,

$20x = 100\\=>x = \frac{100}{20}\\=>x = 5$

So, the sum of the numbers will be,

$=(4x+5x) = 9x = (9\times 5) = 45$
