Question

EGYC Corporation manufactures a certain type of smartphone that requires 66 working capacitors per phone. If one out of 34 capacitors is defective, are 133,450 capacitors enough to assemble 1,987 smartphones?

Answer 1

1. first we find how many defective capacitors are there out of 133, 450:

in 34 capacitors --------- 1 defective
in 133,450 capacitors --------- x defective

so
`x= (133,450*1)/(34)= 3925` is the expected number of defective capacitors.

2.

So there are in total 133,450-3925=129,525 working capacitors.

3.
To assemble 1,987 smartphones the corporation needs 1,987*66= 131,142 working capacitors.

4.
The number of required capacitors is larger than the number of the available ones, so 133,450 capacitors are not enough.
