Solution

Given , the two numbers are $25$ and $40$
The sum of two numbers is $= 25 + 40 = 65$
and the difference of two numbers is $= 40 - 25 = 15$
Now, $5 \div 65 = \frac{1}{13}$
and $5 \div 15 = \frac{1}{3}$
Hence, the given number $5$ is not exactly divisible by the sum and difference of the two given numbers $25$ and $40$ .
