Answer 1

Step-by-step explanation:

Let the number be abcd

1000th digit=a

100th digit=b

10th digit=c

ones digit=d

Given:-

1)a=3+b. 2)d=a+b=3+b+b=2b+3

3)c=a-b=3

The number is

1000a+100b+10c+d

3000+1000b+100b+30+2b+3

1102b+3033

If b=1 then the number is 1102+3003=4105

If b=2 then the no is 2204+3003=5207

If b=3 then the no. is 3306+3003=6309

If b=4 then the no.is 4408+3003=7311

If b=5 then the no. is 5510+3003=8513

If b=6 then the no. is 6612+3003=9615

So, the possibilities of the 4 digit number is
