Questions & Step-by-Step Solutions

A group of friends consists of three pairs of siblings: A and B, C and D, E and F. If A is older than B, and C is younger than D, who is the youngest among them? (2023)
  • Step 1: Identify the pairs of siblings: A and B, C and D, E and F.
  • Step 2: Note the age relationship: A is older than B.
  • Step 3: This means B is younger than A.
  • Step 4: Next, note the age relationship: C is younger than D.
  • Step 5: This means C is younger than D, but we don't know how C compares to A and B yet.
  • Step 6: Since we only have information about A and B, we can conclude that B is younger than A.
  • Step 7: We don't have any information about E and F, so we can't compare them yet.
  • Step 8: Since B is confirmed to be younger than A, we need to check if C or E or F could be younger than B.
  • Step 9: Since we know C is younger than D, we can't determine if C is younger than B without more information.
  • Step 10: However, since we have no information about E and F, we can't conclude they are younger than B either.
  • Step 11: Therefore, based on the information given, B is the youngest among the known siblings.
  • Sibling Age Comparison – Understanding the relationships and age differences among siblings.
  • Logical Deduction – Using given information to deduce the ages of individuals.
