Answer»

The numbers which are divisible by 4 are 104, 108, 112, 116, 120, ..., 228, 232, 236, 240, 244, 248

Their sum = 352 × 35 = 12310

Sum of all numbers between 100 to 250 = 149 × 350 = 522150

HENCE, sum of all numbers between 100 to 250 which are not divisible by 4 = 522150 - 12310 = 509840
