Given:
The sum of two numbers is 24 and their difference is one sixth of the sum.
To find:
The smaller number between the two numbers.
Solution:
Let x and y be the two numbers where x>y.
The sum of two numbers is 24.
...(i)
Their difference is one sixth of the sum.

...(ii)
Adding (i) and (ii), we get



Putting
in (i), we get



The two numbers are 14 and 10.
Therefore, the smaller number between the two numbers is 10.
