Question

7. The sum of two numbers is 16 and their ratio is 3:1, then find the numbers.​

Answer 1

Answer:

4,12

Step-by-step explanation:

Let the two numbers be x and y

x+y=16. x:y=3:1 or x/y=3

which gives x=3y

substituting in x+y=16 for x= 3y,

3y+y=16

4y=16

y=4. x=12

Answer 2

Let the two numbers=3x and 1x [x not equal to 0]
By the problem,

3x+1x=16
4x=16
X=4
One number =4
Another number=4*3
=12

Hope it helps

Thank you
