d.
713,180

Answer 1

b. 761,307 ................

Answer 2

Option: B is correct.

( b. 761,307 )

Explanation:

It is given that:

The number of private investigators is expected to increase from 52,000 in 2006 to 61,000 in 2016.

i.e. the percentage increase is given by:

`(61000-52000)/(52000)* 100\\\\=(9000)/(52000)* 100\\\\=17.3\%`

Now it is given that:

There are 648,982 police officers in 2006.

so the number of police officers in 2016 will be:

`117.3\% * 648982\\\\=(117.3)/(100)* 648982\\\\=761255.886`

Hence, number of police officers in 2016 to have a greater percent increase than that of private investigators is:

Option:b 761,307

(Since in all the other option the value is less than the estimated value i.e. 761255.886 )
