How it will come?

Sum of moment about A is = to zero.
M = Rb*L.
Rb = M/L and Ra = (-M/L).
Take moment @ A from Rb, (M/L*L) = M.
M = Rb*L.
Rb = M/L and Ra = (-M/L).
Take moment @ A from Rb, (M/L*L) = M.

Pinned joint can not be bend or there will be no moment can produce at pin joint so total moment is equal to M.

Answer is wrong, correct answer is M/2.

I think answer is M/2 and its at centre.

Please tell which one is correct?

Answer is M.
Couple is due to two equal forces in different direction so its does not depend on other parameters, i.e couple will be same for entire length.

It is M/2 because Rb = M/L& Ra = -M/L. Moment from mid point = RbxL/2 = M/LxL/2 = M/2 and M/2 - M = -M/2.

Answer is wrong, It should be M/2.
