How many Pi- bonds and Sigma bonds are there in benzene and nitro benzene? Can I get the answer faster please?

12 sigma and 3 pi bonds are present in benzene i.e sigma bonds => C-C=6, C-H=6.... C-C 3 pi bonds

13 sigma and 4 pi bonds are present in nitro-benzene i.e,..sigma bonds=> C-C=6, C-H=5, C-N=1, N-O=1

and  C-C 3 pi bonds and N-O 1pi bond ,...... and there is also an co-ordinate bond present between N and O
