Question

The sum of two numbers which are in the ratio 2:5 is 21 then the numbers are​

Answer 1

2:5 Let the numbers be 2x, 5x Then, 2x + 5x = 21 = 7x = 21 Therefore, x = 21/7 = 3 So, the numbers are : 2x = 2 × 3 = 6 And, 5x = 5 × 3 = 15

Answer 2

Answer:

The numbers are​ 6 and 15.

Step-by-step explanation:

To find -

The number $2x$ & $5x$

Solution -

let,

The two number are $2x$ and $5x$

The sum of two number = $2x + 5x = 21$

Adding the $x$ term we get,

$7x = 21$

To get the value of $x$

we shift 7 to right side

$x = \frac{21}{7}$

$x = 3$

So, two numbers are

$2x = 2 * 3 = 6\\5x = 5 * 3 = 15$

The numbers are​ 6 and 15.
