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
