Question

Whole numbers between 322 and 489 if both 322 and 489 are not included

Answer 1

Number of whole numbers between 10 and 5 are 6,7,8,9
i.e a total of 4 whole numbers
and 10-5=5

Number of whole numbers between 20 and 10 are 11,12,13,14,15,16,17,18,19
i.e a total of 9 whole numbers
and 20-10 is 10

Similarly

489-322=167
Total number of whole numbers
=167-1 = 166
There are 166 whole numbers between 489 and 322

Answer 2
