Answer 2

Option 1

Step-by-step explanation:

Given:-

We double a number and addded to its three times to it, the sum is 45.

To find:-

What is four times that number?

Solution:-

Let the number be X

Double the number = 2X

Three times to the number = 3X

On adding double the number to its three times the number = 2X+3X = 5X

The result = 45

=> 5X = 45

=> X = 45/5

=> X = 9

Answer:-

The required number for the given problem is 9

Check:-

The number = 9

Double the number = 2×9 = 18

3 times the number = 3×9 = 27

Their sum = 18+27 = 45
