    The answer is... on branch A there are 5 birds and on branch B there are 7 birds...

    Method 1:
    Trail and error method... like trying it starting from 1,2, and so on...

    Method 2: Mathematical way

    Let, The no. of birds on branch A = A
    The no. of birds on branch B = B

    Step1

    A+1 = B-1 (because if we add one bird on branch A and decrease one bird on branch B, then they are equal)

    So, A+1 = B-1
    1+1 = B-A
    or, 2+A = B ................ equation 1

    Step2

    2(A-1) = B+1 (because if we subtract one bird on branch A and decrease one bird on branch B, then branch B birds are double of branch A)

    So, 2(A-1) = B+1
    2A-2 = B+1
    2A-B = 1+2
    2A-B = 3
    or, 2A-3 = B ...................equation 2

    now comparing the 2 equations(by mathematical method), we get

    2A-3 = 2+A
    2A-A = 3+2
    A = 5 ..........so there are 5 birds in branch A

    now satisfying the value in equation 1, we get

    2+5 = B
    or, B = 7..........so there are 7 birds on branch B


    ... This effort was especially for Zara...
