#LRDIoftheDay #33

A popular arrangements question. If you can solve this without breaking into a sweat, you should be able to solve most of the arrangements questions.

On a Friday morning, local paediatrician Dr. Johnson N. Johnson had appointments with five infants scheduled at 9:00, 9:30, 10:00, 10:30, and 11:00. Each of the five, including the Ortiz baby, is a different number (viz. 1, 2, 3, 4, or 5) months old.

Being a bit forgetful, Dr. Johnson hired an assistant to keep records. The following information could be recovered from her records.

• Immediately after seeing infant Beth, Dr. Johnson examined the Majors infant, who is 2 months younger than Beth.

• Erica isn’t the one of the five who is 1 month old.

• The doctor saw David later in the morning than the 1-month-old.

• The 9:30 appointment was with the 3-month-old baby.

• The Luce infant isn’t the one who is 5 months of age.

• Dr. Johnson saw the Nash infant, then examined Alice, who is 2 months older than the Nash baby.

• The paediatrician’s 10:00 appointment was with Chad, who isn’t the Majors or the Nash baby.

• The Prior baby isn’t the 1-month-old and wasn’t the doctor’s 9:00 examinee.
