Can You Solve This Logic Test? Many Adults Fail!

This video presents a logic test that many adults find difficult. The problem involves calculating the number of ribbon tapes needed for a party, given the length of each ribbon and the length of each tape. The video highlights the importance of careful reading and understanding the units of measurement when solving such problems.

The Problem

You are hosting a party and need to decorate with ribbons. You have a large spool of ribbon that is 10 meters long. You want to cut the ribbon into 20-centimeter pieces. How many pieces of ribbon can you cut from the spool?

The Solution

Here’s how to solve the problem:

Convert Units: The ribbon is measured in meters, and the pieces need to be in centimeters. Since there are 100 centimeters in 1 meter, the spool is 10 meters x 100 centimeters/meter = 1000 centimeters long.
Divide: Divide the total length of the ribbon by the length of each piece: 1000 centimeters / 20 centimeters/piece = 50 pieces.

Why Many Adults Get It Wrong

Many adults get this problem wrong because they:

Don’t convert units: They try to divide 10 meters by 20 centimeters without converting to the same unit.
Misinterpret the question: They might think the problem asks for the number of 20-meter pieces, rather than 20-centimeter pieces.

Key Takeaway

This logic test highlights the importance of:

Careful reading: Understanding the exact wording of the problem and what it asks for.
Unit conversion: Ensuring all values are in the same units before performing calculations.
