Question:

LCM and HCF of two numbers are 168 and 14 respectively. If one of the numbers is 42, then find the other number.

दो संख्याओं के LCM और HCF क्रमशः 168 और 14 हैं। यदि उनमें से एक संख्या 42 है, तो दूसरी संख्या ज्ञात कीजिए।

Options:

  • (A) 54
  • (B) 58
  • (C) 57
  • (D) 56
  • (A) 54
  • (B) 58
  • (C) 57
  • (D) 56

Correct Answer: Option D

Explanation:

Detailed Explanation: \(N_1 \times N_2 = \text{LCM} \times \text{HCF} \implies N_2 = \frac{168 \times 14}{42} = \mathbf{56}\).

विस्तृत व्याख्या: सूत्र: \(\text{संख्या 1} \times \text{संख्या 2} = \text{LCM} \times \text{HCF}\)
\(42 \times N_2 = 168 \times 14 \implies N_2 = \frac{168 \times 14}{42} = \frac{168}{3} = \mathbf{56}\)।
