The sum of all 4-digit numbers that can be formed using the digits 2, 3, 4, 5, 6 without repetition, is

Step-by-step solution

Given digits are 2, 3, 4, 5, 6 Sum of all 4-digit numbers formed by the using 2, 3, 4, 5, 6 without repetition aligned & =41(2+3+4+5+6) (10^3+10^2+10^1+10^0 ) & =24(20)(1000+100+10+1) & =(480)(1111)=533280 aligned
