Answer:
30000
Step-by-step explanation:
all positive integers less than 300 (300 exclusive)
1,2,3,4,5..........149,150,151.......296,297,298,299
there are (1+299) (2+298) (3+297)...(149+151) 149 pairs of 300 + 150
300 x 149 + 150 = 44850
all positive integers less than 300 which are divisible by 3
3,6,9,12..........294,297 i.e. 3 x (1,2,3,4.......49,50,51.....97,98,99)
3 x ((100 x 49) + 50) = 3 x 4950 = 14850
Answer: 44850 - 14850 = 30000
