Answer :

If three times a number added to 4 is divided by the number plus 4, the result is eight thirds, then the number is 20

Solution:

Given that three times a number added to 4 is divided by the number plus 4, the result is eight thirds

To find: the number

Let the required number be "a"

Let us first break the given sentence

three times a number = 3a

three times a number added to 4 = 3a + 4

number plus 4 = a + 4

three times a number added to 4 is divided by the number plus 4 = [tex]\frac{3a + 4}{a + 4}[/tex]

three times a number added to 4 is divided by the number plus 4, the result is eight thirds which means:

[tex]\frac{3a + 4}{a + 4} = \frac{8}{3}[/tex]

On solving we get,

9a + 12 = 8a + 32

9a - 8a = 32 - 12

a = 20

Thus the required number is 20
