Problem:
What number must be subtracted from the sum of 9,99,645 and 6,35,796 to get 12 lakhs?

Solution:

To find the number that must be subtracted from the sum of 9,99,645 and 6,35,796 to get 12 lakhs, we need to perform the following steps:

Step 1: Find the sum of 9,99,645 and 6,35,796.

To find the sum, we add the two given numbers together:
9,99,645 + 6,35,796 = 16,35,441.

Therefore, the sum of 9,99,645 and 6,35,796 is 16,35,441.

Step 2: Subtract the sum from 12 lakhs.

12 lakhs can be written as 12,00,000. To find the number to be subtracted, we subtract the sum from 12,00,000:

12,00,000 - 16,35,441 = 3,64,559.

Therefore, the number that must be subtracted from the sum of 9,99,645 and 6,35,796 to get 12 lakhs is 3,64,559.

Explanation:

The problem requires finding the number to be subtracted from the sum of 9,99,645 and 6,35,796 to obtain a total of 12 lakhs. To solve this problem, we follow a step-by-step approach.

In Step 1, we find the sum of the given numbers by adding them together. The sum of 9,99,645 and 6,35,796 is calculated as 16,35,441.

In Step 2, we subtract the sum obtained in Step 1 from 12 lakhs, which is equivalent to 12,00,000. By subtracting 16,35,441 from 12,00,000, we find that the number to be subtracted is 3,64,559.

Therefore, the final answer is 3,64,559.
