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
