Correct answer is 1.
ii= m-2j+3,
ie=r-R.
Total indeterminacy= ii+ie.
Where,
m=10, j=6, r=3, R=3.
ii= m-2j+3,
ie=r-R.
Total indeterminacy= ii+ie.
Where,
m=10, j=6, r=3, R=3.

Answer is right.
m=12, j=7, r=5.
D=m+r-2j = 12 +5-2*7=3.
So, the answer is 3.
m=12, j=7, r=5.
D=m+r-2j = 12 +5-2*7=3.
So, the answer is 3.

m=2j - 3
10=12 - 3
= 1.
So the Ans is 1. How it is 3? please explain.
10=12 - 3
= 1.
So the Ans is 1. How it is 3? please explain.

Considering a joint is one where only ends of the members are joining.

M+r-2j.
Member=m=9,
Joint=j=5,
Reaction=r=3,
=9+3-2(5)=12-10=2.
Member=m=9,
Joint=j=5,
Reaction=r=3,
=9+3-2(5)=12-10=2.

How did you tell member=10? Joint=6, reaction=3, please explain.

m= 12, r= 3, j= 7.
Ds= m+r-2j.
Hence Ds= 12+3-7(2) = 15-14 = 1.
Ds= m+r-2j.
Hence Ds= 12+3-7(2) = 15-14 = 1.

@Bikash Bhattrai.
By your logic, m=10, so the answer is 1.
By your logic, m=10, so the answer is 1.

m= 10,
j= 5,
r= 3,
(r+m)-2j.
= (3+10)-2 * 5.
= 3.
j= 5,
r= 3,
(r+m)-2j.
= (3+10)-2 * 5.
= 3.
