Two numbers are in the ration of 5 : 3. If difference between the numbers is 54, then find the smaller number.

Correct option is C

Given:

​Two numbers are in the ration of 5 : 3.  

Difference between the numbers is 54 

Solution: 

Let the first number = 5x 

second number = 3x 

According to the question 

5x - 3x = 54 

2x = 54 

x = 27 

Then the smaller number = 3x = 3 $$\times$$​27 = 81
