Question

How to find the sum of successor of greatest 4- digit number and predecessor of smallest 4- digit number

Answer 1

$\huge{\boxed{\sf{SOLUTION :}}}$

The greatest 4-digit number is 9999

So, the successor of greatest 4-digit number will be = 9999 + 1

• = 10000

Again,

The smallest 4-digit number is 1000

So, the predecessor of smallest 4-digit number will be = 1000 - 1

• = 999

Now the sum of both the successor and predecessor is = 10000 + 999

• = 10999

Answer 2

Step-by-step explanation:

greatest 4 digit number successor=10000

predecessor of smallest 4 digit number =999

their sum= 10000+999=10999
