# What will be the Ratio of Two Number? If

The sum of two numbers is equal to 20 and their difference is 25. the ratio of the two number is

- -9:1
- 7:9
- 3:5
- 2:7

**Answer: ( 1 ). – 9 : 1**

Let two numbers be** X** and** Y.
**

According to Question,

**X + Y = 20 . . . . . . ..(i)**

**and X – Y = 25 . . . . . . . . . (ii)**

Now, solving equations (i) & (ii), we get

**2X = 45**

**X = 22 . 5 ….. . .. … .(iii)**

put the value of X in eqn. (i) , we get

**Y = – 2 . 5**

The ratios of these two number is **X : Y = – 22 . 5 : 2.5 = – 9 : 1**
