hey here is your answer..

Step-by-step explanation:

The smallest 3-digit number divisible by 4 is 100 while the largest is 996.

The sum of all 3-digit number divisible by 4 is an exercise in an AP.

a = 100, d = 4,

996 = a+(n-1)d = 100 + (n-1)*4, or

249–25 = 224 = (n-1)

n = 225

S225 = (225/2)[2*100 + (225–1)*4]

= (225/2)[200+ 896]

= (225/2)*1096

= 12330o.

Answer :123300.
