Positive integer N+1 is divided by 5 , the remainder is 4
Therefore , N+1 = 5q + 4 , where q is quotient -->N+1 can take values 4 ,9 , 14 , 19 , 24 ...
N can take values 3 , 8 , 13 , 18 , 23 ..
The remainder when N is divided by 5 is 3
Answer D

A. 6
B. 5
C. 4
D. 3
E. 2


This can easily be solved by assuming values.
N+1, when divided by 5 leaves remainder 4
Assume N+1 = 9

Therefore, N = 8
N divided y 5 leaves remainder 3
Option D

A. 6
B. 5
C. 4
D. 3

N+1 = 5a+4

i.e. N+1 = 9, 14, 19, 24, ... etc.

i.e. N = 8, 13, 18, 23, ... etc.

When N is divided by 5 Remainder is always 3

Answer: Option D

N+1=5q+4

=> N=5q+4-1 => N=5q+3, so the answer is: the remainder is 3 when N is divided by 5.

Another way:

N+1 =5a+4 ---->N=5a+3
and
N=5a+ x (x is what we looking for)
therefore: 5a+3=5a+x ---> x=3

Can not be 4 as with N=4, N+1 = 5 will not give you a remainder of 4 when divided by 5. But if N=8, N+1=9 will give you a remainder of 4 when divided by 5.

Aha! That is, indeed, when it is in relation with the second part of the question (What is the remainder when N is divided by 5?). Thank you. Makes sense now.
