3C + 25 ==> C + 5 = 12 +5 = 17 > 16. So, 17 -16 =1 and 1 carry to next MSB.
==> 3 + 2 + 1 (Carry from previous addition) ==> 6.
Total = 61.
==> 3 + 2 + 1 (Carry from previous addition) ==> 6.
Total = 61.

First find the decimal equivalent of 3C which will be = 3 * 16^1 + 12 * 16^0 i.e. 60.
Now find the decimal equivalent of 25 which will be= 2 * 16^1 + 5 * 16^0 i.e. 37.
Now add both these in the decimal form we get the decimal addition as= 60+37 i.e. 97.
Now convert this decimal 97 into hexadecimal format i.e. 61.
Now do the same for all.

First addition is wrong.
