Answers
Answer:
A. True
B. False
C. True
D. False
E. False
Step-by-step explanation:
A.
We know that,
In Roman numbers, the same symbol is not repeated more than 3 times together. It is a basic rule to avoid confusion and time lag.
So, it is True
B.
We know that,
Prime numbers are numbers that have 1 and the numbers itself as it's factors
So,
Prime numbers = 2, 3, 5, 7,...
This tells us that,
4 is not even prime and that the smallest even prime number is 2.
So, it is False.
C.
We have,
397584
We need to find if it is divisible by 6,
We know that,
If a number is divisible by 2 and 3 then that number is also divisible by 6.
Now,
Divisibility rule of 2 says that if a numbers ends in 0, 2, 4, 6, or 8 it is divisible by 2
Here,
397584 ends with 4, so it is divisible by 2
Again,
Divisibility rule of 3 says that if the final total sum of a number is equal to 3, 6, or 9 then it is divisible by 3.
Here,
3 + 9 + 7 + 5 + 8 + 4 = 36
Again,
3 + 6 = 9
So,
397584 is divisible by 3
And since 397584 is divisible by both 2 and 3, it is divisible by 6 also.
So, it is True.
D.
We know that,
The number after the decimal point is called tenths and the number after that is called hundredths and next, thousandths and so on....
But in 41.036 3 is Hundredths not tenths
So, it is False.
E.
We know that,
Loss = C.P - S.P
Now, if we rearrange a little bit we get,
C.P = Loss + S.P
But we are given,
C.P = S.P - Loss
which incorrect
So, it is False
Hope it helped you and believing you understood it...All the best
