Question

Can u guys PLEASE do this question 29

Answer 1

264 transistors.

Explanation:

By proportion the total number made if 16 are faulty is (35/2) * 16

= 280.

The number of good ones is 280 - 16

= 264 transistors.

Answer 2

264 good ones

Explanation:

2 in 35 are faulty = in a batch of 35, 2 will be faulty = there are 33 good for every 2 faulty ones there are

16 faulty have been made - to figure out how many batches there have been do 16/2=8

8 batches of 35, 8 × 35 = 280 total

280 total - 16 faulty = 264 good

OR do 8 batches × 33 good per batch = 264 good

at least thats how i interpreted it!
