Question:

There are 20 books arranged in a line. Book A is 5th from the start and Book B is 8th from the end. How many books are between A and B?

एक पंक्ति में 20 पुस्तकें व्यवस्थित हैं। पुस्तक A आरंभ से 5वीं और पुस्तक B अंत से 8वीं है। A और B के बीच कितनी पुस्तकें हैं?

Options:

  • 6
  • 7
  • 8
  • 9
  • 6
  • 7
  • 8
  • 9

Correct Answer: b)

Explanation:

Sum of ranks from both ends = \(5 + 8 = 13\).
Books between A and B = \(\text{Total} – 13 = 20 – 13 = 7\).

दोनों छोरों से स्थानों का योग = \(5 + 8 = 13\)।
बीच में रखी पुस्तकों की संख्या = \(20 – 13 = 7\)।
