The first number is 105, and the second number is 135, the question is to tell the difference of the two numbers.

135 - 105 = 30

Answer 2

Answer:

C) 30

Step-by-step explanation:

Let the no.s be :

7/9 = 7x/9x

Given,

sum of the two no.s = 240

7x+9x = 240

16x= 240

x= 15

Now,

the no.s are:

7x= 7×15 = 105

9x= 9×15 = 135

Therefore the difference between them :

135-105= 30

Hence,

C)30 is the correct option
