Question
An analysis showed that 0.06 per cent of the T-shirts made by one company were defective. A student says this is 6 out of every 100. What is the student’s error?
Solution
According to the analysis,
Defective T-shirts made by one company = 0.06% = `0.06/100 = 6/10000`
But according to the student, defective T-shirts = 6 out of every 100 = `6/100`
Hence, student's error is that, the defective T-shirts are 6 out of every 10000 (not 100).
