We have to find the value of given expressions by suitable arrangements.

Solutions :

a. $87+64+36$

The given should be arranged in such a way that the units digit of the sum of the units digits of the numbers is 0.

Here,

$87+64+36 = 87+(64+36) = 87 + 100 = 187$.

The value of $87+64+36$ is $187$.
