Dear Admin,

It is not fair fair on your part to change language of qn on next day .
According to statement
Sum of all the numbers formed by the integers 2,3,4,5,8 is ....

The sum can not be calculated as there are infinite numbers that can be made with these integers.

On next day , you changed the statement to help some members with wrong answers with new statement

(Repetition is not allowed)

Pls respond with unbiased approach.

Pls accept mistake if statement printed is wrong instead of punishing those who gave correct answer as per given statement
