Which of the following is a prime number?

  • A1
  • B9
  • C15
  • D17
Permalink
Correct Answer: Option D — 17
Explanation: 17 is a prime number having exactly two factors: 1 and itself. The number 1 is neither prime nor composite. 9 equals 3×3 and 15 equals 3×5 so both are composite. Prime numbers are fundamental in number theory cryptography and competitive exam questions on divisibility HCF LCM and factorization.

Solve: 2x + 5 = 15, find x

  • Ax = 4
  • Bx = 5
  • Cx = 6
  • Dx = 7
