Question

A log is 16 m long correct to the nearest metre.It has to be cut into fence posts which must be 70 cm long correct to the nearest 10 centimetre. what is the largest number of fence posts that can possibly be cut from the cut

Answer 1

Here, it is given that the log is $16m$ long, which is cut into fence,

and each of the fence posts is $70 cm$ long which is corrected to the nearest $10 cm.$

As we have to find the largest possible number of fence posts.

The log is $16m$ long, corrected to the nearest metre.

Assume that  

⇒ Longest possible $= 16.49 m$

So, by converting it into centimetre we get,

⇒ Longest possible$= 1649 cm$

 Similarly, assume for

⇒ Shortest possible $= 65 cm$

Now, for the required,

Largest Possible $= \frac{1649}{65}$

Largest Possible $= 25$
