Sum of all the numbers that can be formed using all the digits `2, 3, 3, 4, 4, 4` is

A

`11111100`

B

`22222200`

C

`55555500`

D

`20333280`

Text Solution

Verified by Experts

The correct Answer is:
B

`:. "sum" = (2 xx 10) + (3 xx 20) + (4 xx 30) = 200`
of unit place
`:.` Reqd. sum
`= 200 (10^(5) + 10^(4) + 10^(3) + 10^(2) + 10^(1) + 10^(0))`
`= 200(111111) = 22 22 22 00`
