Question 14
Number of whole numbers between 38 and 68 is
(A) 31
(B) 30
(C) 29
(D) 28

Answer 1

Whole numbers between 38 and 68 are 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66 and 67.
$\therefore$ Total whole numbers between 38 and 68 = 29
Alternate method
Let a=38 and b=68
Then, number of whole numbers between a and b
=b-a-1 [when b>a]
$\therefore$ Number of whole numbers between 38 and 68
=68-38-1
=29
