Answer 1

Answer:

they will finish work in 12 minutes

Answer 2

Answer:

5 machine of the same capacity will take 36 minutes to do same job of painting .

Step-by-step explanation:

given that

working together three machines can finish panting of house in 60 minutes

lets assume complete work of painting be represented by variable W.

so work done by 3 machines in 60 minutes = W ( complete work)

=> work done  by 1 machine in 60 minutes = $\frac{W}{3}$

=> work done  by 1 machine in 1 minutes = $\frac{W}{3*60}$=$\frac{W}{180}$

so work done by 5 machines in 1 minute = $\frac{w}{180}  * 5 = \frac{w}{36}$

so number of minutes taken by 5 machines to do complete work = Complete work divided by work done by 5 machines in 1 minute = $\frac{W}{\frac{W}{36} }$ = 36 minutes

So 5 machine of the same capacity will take 36 minutes to do same job of painting .
