Question

In testing for quality​ control, it was found that 19 of every 412 computer chips produced by a company in a day were defective. If a total of 646 defective parts were​ found, what was the total number of chips produced during that​ day?

Answer 1

14,008

Explanation:

Defective = 19 when total production = 412

Defective chips : total chips produced

19 : 412

Defective = 646 when total production = x

Defective chips : total chips produced

646 : x

Equate the ratios

19 : 412 = 646 : x

19 / 412 = 646 / x

Cross product

19 * x = 412 * 646

19x = 266,152

x = 266,152 / 19

= 14,008

x = 14,008

Total chips produced for the day when number of defective is 646 is 14,008
