Mr. I does a job in x hours while Mr. L can do it in y hours. How much of the job could they do together if they were to work fo

dimulka [17.4K]

Answer: Work done by both of them in k hours is

$\frac{k(x+y)}{xy}$

Explanation:

Since we have given that

Number of hours Mr. I does a job = x hours

Number of hours Mr. L does a job = y hours

Work done by Mr. I is given by

$\frac{1}{x}$

Work done by Mr. L is given by

$\frac{1}{y}$

Work done if they do together is given by

$\frac{1}{x}+\frac{1}{y}\\\\=\frac{x+y}{xy}$

Work done if they work together for k hours is given by

$\frac{x+y}{xy}\times k\\\\=\frac{k(x+y)}{xy}$

Hence, work done by both of them in k hours is

$\frac{k(x+y)}{xy}$

slega [8]

Answer:

Step-by-step explanation:

A store has a 20% sale on everything.

So since you are saving 20%, you will only be paying 80% of the original price.

To find the sale price use the following formula:

Sale price = 80% x original price

They told us the original price = 350 AED

This means:

Sale price = 80% x 350

I think it would be easiest to change 80% into a fraction if you don't have a calculator :)

80% = $\frac{80}{100} = \frac{4}{5}$

This means that the

Sale Price= $\frac{4}{5}$ x 350 = 280 AED
