Question

A quality control inspector found that 1.3% of 1500 computers inspected were defective. How many computers were defective?

Answer 1

Given that percent of computer infected which is found by quality control inspector = 1.3%

Total number of computers = 1500

Now we have to find the number of Defective computer. To find that we will just need to find the product of given defective percent by the total number of computers.

Total number of defective computers = 1.3% of 1500

Total number of defective computers = 0.013* 1500

Total number of defective computers = 19.5

Hence final answer is approx 20 computers.

Answer 2

1.3% of 1500 = 0.013 x 1500 = 19.5

Answer: 19.5 computers were defective,
