Transition diagram will be like this.

Case1: when Q=0.

For s = 0. ( here j = 0, k = 0. Latch mode, same state)

For s = 1. ( j = 1, k = 1, Toggle Mode, change the state).

Case2. when Q = 1.

For s = 0. ( here j = 0, k = 0. Latch mode, same state)

For s = 1. ( j = 1, k = 1, Toggle Mode, change the state).

When Q = 1 and s = 0 ==> I0 = 1 and I1 = 0 , s = 0 ==> Y = I0 ==> Y = J = K = 1 toggle Qn = 0 hence state change on Q =1 on s = 0

Case2. when Q = 1.
For s = 0. ( here j = 0, k = 0. Latch mode, same state)

In this case y will be 1 right, which will toggle the output..isn't it?
