Question

two numbers are in the ratio 4:5. if 5 is added to each number, the ratio becomes 13:16 find the number. ​

Answer 1

Step-by-step explanation:

Let the numbers be 4x and 5x

So, the ratio = 4x:5x

Now , it becomes

4x + 5 : 5x + 5 = 13 : 16

4x+5/5x+5 = 13/16

65x + 65 = 64x + 80

65x - 64x = 80 - 65

x = 15

So , the numbers are ,

4x = 4*15 = 60

5x = 5*15 = 75
