Number of 4 digits that can be formed using the digits a, b, b, c = 4!/2! = 12
--> Out of these 12, 'a' occurs in each places (thousands, hundreds, tens and units) 3 times
--> Sum of all values of a's places = 3*1000a + 3*100a + 3*10a + 3*a = 3333*a
Same is for c
--> Sum of all values of c's places = 3333*c
Note that, b occurs 6 times each in thousands, hundreds, tens and units places
--> Sum of all values of b's places = 6*1000a + 6*100a + 6*10a + 6*a = 6666*a
--> Sum of all digits places = 3333*a + 6666*b + 3333*c
= 3333*(a + 2b + c)
= 3333*(3 + 10 + 6)
= 63327

Total possible numbers = 4!/2! = 12
5 will appear 6 times at each digit place and 3 and 6 appear 3 times at each digit place.
Sum of all 4 digits numbers = 1111 * (6*5 + 3*3+3*6) = 1111 * 57 = 63327
5 will appear 6 times at each digit place and 3 and 6 appear 3 times at each digit place.
Sum of all 4 digits numbers = 1111 * (6*5 + 3*3+3*6) = 1111 * 57 = 63327
