Question

what least number should be added to 5483855 such that place value of 9 in the resulting becomes 900000

Answer 1

If we can recall our knowledge about place value we can simply solve this problem,

if we take numbers 900000 and 984000, place value of 9 for both numbers is 900000.

In the question,

for the number 5483855, place value of hundred thousandth is 400000.

If we can turn this 4 into a 9, place value of hundred thousandth is 900000

So the least number that the place value of hundred thousandth is 900000 will be 5900000. In order to get there you have to add 416145. Which can be obtain by,

5900000 - 5483855

So the answer is 416145
