(#M40023760) TCS QUESTION Keep an EYE

The number of times 2 occurs in 1000 to 9999.
I came across two methods.
Total 4 digit numbers that we can form is (9*10*10*10)
Total 4 digit numbers that we can form with out 2 is (8*9*9*9)
so 4 digit nos with 2 we can form (9*10*10*10)-(8*9*9*9) = 3168

OR

Number of 2's at units place(1000 to 9999)=900
Number of 2's at tenths place(1000 to 9999)=900
Number of 2's at hundreds place(1000 to 9999)=900
Number of 2's at thousands place(1000 to 9999)=1000

therefore total number of 2's =(900+900+900+1000)=3700

Which is the right method?
