Question

The sum of two numbers is 20 and their difference is 2.5. Find the ratio of the
numbers.​

Answer 1

Answer:

Let the no be x,y then (x+y)=20...(1)

6(x−y)=2.5...(2)

(1)+(2)⇒2x=22.5⇒x=11.25

⇒y=8.75

∴x:y=11.25:8.75

⇒x:y=8:7

Answer 2

Answer:

9:7

Explanation:

let x and y be the numbers

given, x + y = 20          ----(1)

          x - y = 2.5          ----(2)

adding these equation gives

2x = 22.5

x= 11.25

subtracting these equations gives

2y = 17.5

y = 8.75

therefore x=11.25, y=8.75

x:y = 11.25 : 8.75

multiply ratio by 4

x:y = 45:35

divide ratio by 5

x:y = 9:7

Now, it is the simplest ratio
