But the question has not mentioned the least possible value, so how we would figure it out? And, what about when 12/2=6, which is even and when divided by 4 does not give remainder 0?
Remainder is the number you are left over with after dividing a certain number(dividend) by another number(divisor). For ex- 13 divided by 3 has a remainder 1. You get a remainder only if the number is not totally divisible . Similarly, You can't have a remainder if you divide 12 by 6 because 12 is totally divisble by 6.
In this case its given n/2 is an even integer . This means n/2 can be equal to ... -2, 0, 2, 4,... n so on.
Substituting any values , ( u can test cases
)
1) n/2=0 , This means n= 0. And ofcourse, 0 is divisible by 4 in zero times.
2) n/2=-2 , This means n= -4. And ofcourse, -4 is divisible by 4 in -1 times.
3)1) n/2=2 , This means n= 4. And ofcourse, 4 is divisible by 4 in 1 times
All values are totally divisble and there are no remainders or remainders =0 (Option A)
Hope this helps
