If A Positive Integer N Is Divided By 5, The Remainder Is 3. Which Of The Numbers Below Yields A Remainder Of 0 When It Is Divided By 5?

Answer»

n DIVIDED by 5 yields a remainder equal to 3 is written as follows 

n = 5 k + 3 , where k is an integer. 

ADD 2 to both sides of the above equation to obtain 

n + 2 = 5 k + 5 = 5(k + 1

The above suggests that n + 2 divided by 5 yields a remainder equal to zero. 

n divided by 5 yields a remainder equal to 3 is written as follows 

n = 5 k + 3 , where k is an integer. 

add 2 to both sides of the above equation to obtain 

n + 2 = 5 k + 5 = 5(k + 1) 

The above suggests that n + 2 divided by 5 yields a remainder equal to zero.
