उत्तर

Let the smaller number be x. Then the larger number is: x + 15

The sum of the two numbers is given as 195, so:

x + (x + 15) = 195.

Simplify the equation:

2x + 15 = 195.

Subtract 15 from both sides:

2x = 180.

Divide by 2: x = 90

The larger number is: x + 15 = 90 + 15 = 105

The two numbers are: 90 and 105
