    E will be greater than O by 11.

    Step-by-step explanation:

    Given,

    0 = - 3+5+7+9+105

    E = 4+6+8+10+106

    As we have to find which one is greater O or E, without actually adding them. So, we will just compare the each of the respective terms of both O and E.

    As both O and E have same number of terms, so by comparing them we can see

    -3 < 4

    5 < 6

    7 < 8

    9 < 10

    105 < 106

    As each of the respective terms of O is smaller than the respective terms of E, so E will be greater than O.

    Now, by subtracting each respective terms of O from E

    4 - (-3) = 7

    6-5 = 1

    8-7=1

    10-9=1

    106-105=1

    =>7+1+1+1+1=11

    Since, the sum of the difference of each respective terms of O and E is 11, so E will greater than the O by 11.
