उत्तर
\[(i)\text{We know that when } \overline{ab} - \overline{ba} \text{ is divided by 9, the quotient is a - b .} \]
\[\text{Therefore, when (94 - 49) is divided by 9, the quotient is (9 - 4 = 5) . }\]
\[(ii)\text{ We know that when } \overline{ ab }-\overline{ ba } \text{ is divided by (a - b), the quotient is 9 .} \]
\[\text{ Therefore, when (94 - 49) is divided by (9 - 4 = 5), the quotient is 9 .}\]
