M+r -2j is applied to truss.

I think M+r-2j is used for Truss not for FRAME.

Degree of external indeterminacy = r - 3 = 6 - 3 = 3.
Degree of internal indeterminacy = m - (2j - 3) = 3 - (2*4 - 3) = -2,
Degree of static indeterminacy = External + Internal = 3 -2 = 1.
Alternatively,
Degree of static indeterminacy = (m + r) - 2j = (3 + 6) - 2 * 4 = 1.
Degree of internal indeterminacy = m - (2j - 3) = 3 - (2*4 - 3) = -2,
Degree of static indeterminacy = External + Internal = 3 -2 = 1.
Alternatively,
Degree of static indeterminacy = (m + r) - 2j = (3 + 6) - 2 * 4 = 1.

For frame;
3(m-j)+r-c
Here,
m=3
J=4
r=6
C=2
Solving, degree of indeterminacy = q.
3(m-j)+r-c
Here,
m=3
J=4
r=6
C=2
Solving, degree of indeterminacy = q.

m+r-2j = 3+6-8 = 1.

We have x & y reaction at each of a, b & c giving 6 unknowns. Then the correct answer must be 3. But if the question was "Number of side ways" then the answer is 1.

M + r - 2j, for true.

Here m+r-2j = 3+6-8 = 1.

Its frame not a trus so formula= 3m+re-3j.
(3*3) +4- (3*4) =1.
(3*3) +4- (3*4) =1.

m = 3.
r = 6,
j = 4,
= 6+3-2*4.
= 1.
r = 6,
j = 4,
= 6+3-2*4.
= 1.
