Is the product of two numbersxandya prime number?1) x/y = prime2) x an...
Correct Answer :- b
Explanation : Both the statements are required to answer the question.
Because it is given x and y are consecutive integers
Let x = 2, y = 1
When dividing x/y = 2/1
= 2(prime).

Solution:
To determine whether the product of two numbers x and y is a prime number, we need to know the values of x and y.
Statement 1:
x/y = prime
This statement provides some information about the relationship between x and y, but it does not tell us the values of x and y. Therefore, we cannot determine whether the product of x and y is a prime number based on this statement alone.
Statement 2:
x and y are consecutive integers
This statement tells us that x and y are consecutive integers, which means that they differ by 1. For example, if x = 5, then y = 6. If x = -3, then y = -2.
If x and y are consecutive integers, then one of them must be even and the other must be odd. If the even number is not 2, then the product of x and y will be even and therefore not prime. If the even number is 2, then the product of x and y will be 2 times the odd number, which is also not prime. Therefore, we can conclude that the product of x and y is not a prime number if x and y are consecutive integers.
Combined:
Using both statements together, we know that x and y are consecutive integers and that x/y is a prime number. However, we still do not know the values of x and y. Therefore, we cannot determine whether the product of x and y is a prime number based on these two statements alone.
Conclusion:
From the above discussion, we can conclude that both statements are required to answer the given question.

Statement 1 says x/y is prime. So if we take 6/2 = 3 I.e Prime. But 6*2 is not Prime.
Statement 2 says both are consecutive -- 1*2 is prime but 2*3 is not Prime.
Taking both together, only 2/1 case forms -- product is prime.
Hence answer should be B.
