Correct option is C
Given
Number = 1000
Divisor = 45
Formula Used
Number to be added = Divisor - Remainder
Solution
Divide 1000 by 45:
1000 = 45 × 22 + 10
The remainder is 10.
To make the number exactly divisible by 45, we need to add:
45 - 10 = 35
Thus, 1000 + 35 = 1035, which is perfectly divisible by 45.
Final Answer
So the correct answer is (c)
