Solution:

It is given that three numbers are in the ratio 3 : 5 : 7.

Let the three numbers be 3x , 5x , 7x.

Here the largest number is 7x and the smallest number is 3x.

Given : Larger number = 42

So, 7x = 42 and

x = 6

So, the smaller number = 3x = 3(6) = 18

Hence, Larger number = 42 and smaller number = 18

Difference between smaller number and larger number,

= 42 - 18

= 24

So, the correct option is D). 24
