Given:

The sum of the number 985 and two other numbers obtained by arranging the digits of 985 in cyclic order is divided by 111, 22 and 37 respectively.

To do:

We have to find the quotient in each case.

Solution:

The given number is 985

The other two numbers by arranging its digits in cyclic order are $859, 598$

These numbers are of the form $\overline{abc},\overline{bca},\overline{cba}$

Therefore,

If $985 + 859 + 598$ is divided by 111, then quotient is $a + b + c = 9 + 8 + 5 = 22$

If this sum is divided by 22, then the quotient is $111$.

If this sum is divided by 37, then the quotient is $3(a+b+c)=3(22)=66$.
