For a binary string x = a0a1 · · · an−1 define val(x) to be the value of x interpreted as a binary number, where a0 is the most significant bit. More formally, val(x) is given by How many minimum states will be in a finite automaton that accepts exactly the set of binary strings x such that val(x) is divisible by either 4 or 5. Ans is 5 or 20?

Twin primes are pairs of numbers p and p+2 such that both are primes-for instance, 5 and 7, 11 and 13, 41 and 43. The Twin Prime Conjecture says that there are infinitely many twin primes. Let TwinPrime(n) be a predicate that is true if n and n+2 are twin primes. Which of the ... TwinPrime(n)) ∃m. ∀n. n ≤ m implies TwinPrime(n) ∃m. ∀n. TwinPrime(n) implies n ≤ m ∀m. ∃n. n ≤ m and TwinPrime(n)
