Sorry for the headaches but i heard this question is a question in a worksheet for 12 yrs olds.

The answer is 3588.
Use excel to list all the numbers from 33 to 124 and delete all the even number followed by using autosum to add all the odd numbers

= sum of the odd numbers from 33 to 123
= 33 + 35 + ... ... + 121 + 123
= 3588

first u find the sum of nos from 1 to 124 and then subtract the sum of nos from 1 to 32. u will get the sum of nos from 33 to 124. from that u subtract the sum of even nos from 33 to 124.
1. sum of nos from 1 to 124 = (124*125)/2 (use mathematical formula
(n*(n+1))/2. this formula is for calculating the sum of n numbers
= 7750
2. sum of nos from 1 to 32 = (32*33)/2
= 528
3. sum of nos from 33 to 124 = 7750-528
=7222
4. sum of even nos from 33 to 124 = sum of (34,36,38,40,42,44,46,48,50,52,54,56,58,60,62,..........124)
= sum of 2(17,18,19,20,21,22,23,24,25......62)
= sum of 2 (sum of nos from 1 to 62 - sum of nos from 1 to 16)
= sum of 2 ( 1953 - 136)
= sum of 2 (1817)
= 3634
4. sum of odd nos from 33 to 124 = 7222-3634
= 3588

Good one. I tried to figure it out but now my brain hurts and I must say good bye.
