Answer 1

Hi ,
______________________________
1 ) The number of natural numbers from

' a ' to ' b ' where a < b is b - a + 1.

Let a = 400 and b = 500

The number of natural numbers from 400

and 500 = b - a + 1

= 500 - 400 + 1

= 100 + 1

= 101

Option ( 1 ) is correct .

2) The number of natural numbers between

a and b where a < b is b - a - 1

The number of natural numbers between

400 and 500 = 500 - 400 - 1

= 100 - 1

= 99

I hope this helps you.
