Question

In an automobile parts factory, for every 175 carburetors 3 are found to be defective. At that rate how many carbureatots out of 1,050 could be expective to be detective.

Answer 1

At the same rate 18 carburetors out of 1,050 could be expected to be detective.

Explanation:

The number of carburetors tested = 175

Defective pieces out o f 175 = 3

So, ratio of defected to tested = 3 : 175

Now, the number of carburetors tested in second batch = 1,050

Here, let the defective pieces = m

So, by the Ratio of Proportion,

`(3)/(175)  = (m)/(1050)`

or,
`m = (1050  * 3)/(175)  = 18`

⇒ m = 18

Hence, at the same rate 18 carburetors out of 1,050 could be expected to be detective.
