Suppose you are given four statements about a number: a) It is the number 9. b) It is a prime number. c) It is an even number. d) The number is divisible by 15. Only two statements out of four are true. What is the least possible positive value for the unknown number?
as 9 isnt divisible by 15 or even, it cant be true. it cant be a prime number and even so thats not true either. the number must be 30 because it is divisible by 15 and even and the least possible value.
