$68.28
$308.01
$90.51
$5,420

Answer 1

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

Number of words the manual contains= 16000

Number of words typed by a clerk in one hour and 20 minutes = 4160

According to question we will use "Unitary method":

Number of hours is need to type 4160 words is given by

$1\frac{20}{60}\\\\=1\frac{1}{3}\\\\=\frac{4}{3}$

Number of hours is needed to type 1 word is given by

$\frac{4}{3}\times 4160$

Number of hours is needed to type 16000 words is given by

$\frac{4\times 16000}{3\times 4160}\times 17.65$

Now, the clerk cost per hour = $17.65

So, the manual cost that will take to recreate by the firm is given by

$\frac{4\times 16000}{3\times 4160}\times 17.65\\\\=\ 90.51$

Hence, Third option is correct.
