Three workers have to do a certain job. The first worker can finish the job in 8 hours. The second worker can finish the job in
mestny [16]

Working together three workers would take 1 hour 36 minutes to finish the job

<em><u>Solution:</u></em>

Given that first worker can finish the job in 8 hours

So in one hour, first worker can do \frac{1}{8} th of the work

The second worker can finish the job in 4 hours

So in one hour, second worker can do \frac{1}{4} th of the work

The third worker can also finish the job in 4 hours

So in one hour, third worker can do \frac{1}{4} th of the work

<em><u>The three workers working together in 1 hour can do:</u></em>

\frac{1}{8} + \frac{1}{4} + \frac{1}{4} = \frac{1 + 2 + 2}{8} = \frac{5}{8}

The three worker can thus do \frac{5}{8} th of the work in one hour

Hence the three of them together can finish the work in \frac{8}{5} hours

\frac{8}{5} = 1\frac{3}{5} hours

Thus working together three workers would take 1 hour 36 minutes to finish the job

Step-by-step explanation:

we know that

A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

a_n=r^{n-1}

where

a_n----> n^{th} term of the sequence

r ---> is the common ratio

a ---> the first term of the sequence

a=50\\r=100\%-10\%=90\%=90/100=0.90

substitute

a_n=50(0.90)^{n-1}

For n=12

substitute

a_n=50(0.90)^{12-1}=16
