This is the correct answer. If we subtract 1 from 10,000 we get 9,999.

This is the right answer. When we add all the figures we will get 9,028.

i.e 9000 + 9 + 19 = 9028

This is the right answer. The question is ... one more than the number is 85200, so to solve it we will subtract one from 85,200 to get the answer.

So, 85,200 - 1 = 85,199

This is a right answer. If we subtract 4,956 from 6,935 we will get the number which added to 4,956 gives 6,935.

ie. 6,935 - 4,956 = 1979.

Here the answer is 1,979

This is the right answer. If we multiply 99 by 5 then we will get the answer which we will get after adding 99 five times.

This is the correct answer. If we subtact the amount man earns in a month from the amount he spends, we will get the amont he saves in a  month.

6,250.25 - 5,088.75 = Rs. 1,161.50

This is the right answer.

This is the correct answer. As we know, the difference between the two numbers and we also know the bigger number, so to get the smaller number we subtract bigger number and the difference we get the answer.
30,451 - 4,937 = 25,514

This is the right answer. To get the distance traveled by Rupali, first we have to find out the distance of Bangalore from Rupali's village, that is 1,409 km;  then we will add the distance of Sofia's village from Bangalore that is 235 Km. So, to get the total distance traveled by Rupali: 1,409 Km + 235 km = 1,644 Km

This is a right answer, as the smallest three digit number is 100 and the number after that is 101.
