The sum of two numbers is 300 and the two numbers have a ratio of 20:10. Find the larger number.

Komok [63]

Step-by-step explanation:

Let the two numbers be 20x and 10x

Then by the question,

20x + 10x = 300

or, 30x = 300

or, x = 300/ 30

x = 10

Now the larger number

20x = 20* 10 = 200.

Hope it will help you :)
