Find the sum of all 2 digit numbers divisible by 3.	Choose the correct option:
A) 1665  B) 1765  C) 1865  D) 1965  E) 1555
All 2 digit numbers divisible by 3 are :   12, 51, 18, 21, ..., 99.   This is an A.P. with a = 12 and d = 3.   Let it contain n terms. Then,   12 + (n - 1) x 3 = 99 or n = 30.   Required sum = 30/2 x (12+99) = 1665.   1665nswer is 1665
