(1) NPP is divisible by 8.

(2) NPP is divisible by 4.



Divisibility rule for 8 - Last 3 digits of a number must be divisible by 8
Divisibility rule for 4 - last 2 digits of a number must be divisible by 4

we can see both B and A are sufficient

ex - 144 mod 8 = 0

1144 mod 4 = 0


D imo

Rule of divisibility of 8 - Last 3 digits of the number must be divisible by 8
Rule of divisibility of 4 - Last 2 digits of the number must be divisible by 8
If the number is divisible by 8 then it will also be divisible by all its factors i.e. by 2,4 and 8


Question: is NNPP divisible by 4?

Statement 1: NPP is divisible by 8

i.e. the number is divisible by 8 hence it has to be divisible by 4 as well

SUFFICIENT

Statement 1: NPP is divisible by 4

i.e. the number is divisible by 4 hence

SUFFICIENT

ANswer: Option D
