Identify a number that results in a 4-digit number when 156,350 is subtracted from it

This question may have many answers. Question doesn't says to find all such numbers so I will show you how to get one such number.

Let the required numbers is x.

we have to subtract 156350 from it to get a 4-digit numbers

Then we get equation:

x-156350=Four digit number

we can pick any Four digit number as that 4-digit number is not given.

So let's use 4-digit number = 1000

then above equation changes to

x-156350=1000

now let's solve it

x-156350+156350=1000+156350

x=157350

Hence 157350 is the possible answer.

Similarly you can find other answers using another 4-digit number using above process if needed.
