their sum. Divide the sum of the numbers by the sum of their digits. What would be
the result ?
21​

Answer 1

Answer:

Let the numbers 2,5 and 8.

then all possible two digit numbers are:

25 and 52

58 and 85

28 and 82.

now, sum of all these numbers

25+52+58+85+28+82=330.

and sum of the digits 2+5+8= 15.

so when we divide 330 by 15

the correct answer will be 22.
