Question

Given that x is a prime number and y is a composite number state True or False for each statement.
(A)7y is a prime number
(B)x+x+x is a composite number

Answer 1

(A) False. 7y is not necessarily a prime number because it depends on the specific value of y. If y is divisible by 7, then 7y would be composite.
(B) True. The sum of three prime numbers will always be composite.
