|_______|_______|_____|

since the numbers are divisible by 2,

the unit's place can be filled by using any

one of digits 2 or 8 in 2 ways.

Without any restriction, each of the

remaining places can be filled by using

any one of the digits 2, 3, 5, 7, 8 in 5

By fundamental principle of multiplication,

Total number of 3 digits numbers formed
