At exactly 3:00 PM on a Monday, the marketing team finalized and approved the launch plan for a new campaign and the following evaluation process. The campaign would be launched at 5:00 PM on some day after that Monday, and the customer questionnaire would be sent at 9:00 AM on some day after the campaign launch.
In the table, select for
Launch the number of hours between the 3:00 PM decision on Monday and the 5:00 PM campaign launch, and select for
Questionnaire the number of hours between the decision on Monday and the 9:00 AM time the questionnaire is sent that would be jointly consistent with the given information. Make only two selections, one in each column.
Between 3:00 PM and 5:00 PM on some day after Monday is of the form 24m + 2 hours, where m is the number of full days after Monday.
Between 3:00 PM and 9:00 AM on some later day is of the form 24n + 18 hours, where n is the number of full days after Monday.
We need one number in the options that fits 24m + 2 and
a larger number that fits 24n + 18. Among the options:
• 98 = 24 * 4 + 2, so it fits the launch condition.
• 138 = 24 * 5 + 18, so it fits the questionnaire condition.
This is the only valid pair.
Correct answer: Launch
"98"Questionnaire
"138"
