Statement: p is prime.reason:1) p=2*a, 2) p>10
Statement: a-2b=10.reason:1) a-3b=14, 2) b>0

• 1). Since any number multiplied by 2 is even number, which cannot be prime number. So statement 1 alone is sufficient to answer the question.
  2) statement 1 alone is necessary to answer the question. Because solving the equations, we get the a,b values.

• 1) in the 1st statement it can be a=1, but we cannot be sure. so p may or may not be prime.
  in the second ststement , it confirms that p cannot be prime

• when we put a=1 we have p=2 which is satisfying the condition that no is prime and there is no such values for disapproving this and when we take p>10 it may be 11,12 and so on in which all are not prime so statement one is sufficient alone to satisfy this condition
