Question 7. A positive integer when divided by the smallest odd prime, leaves a remainder r. Which
of the following CANNOT be ?
(a) 0 (b) 1 (c) 2 (d) 3

From byju's maths workbook..

Answer 1

The smallest prime no is 2

But the smallest odd prime no. is 3.

Therefore we won't get the remainder as 3 when a positive integer is divided by 3, as it can be further divided.
The correct option is (d) 3
