Question

Radha completes a work in 15 days ,how much work she will do in 3 days​

Answer 1

Answer:

The work done by Radha in 3 days is 1/5 work .

Step-by-step explanation:

Given -

Radha completes a work in 15 days

To find -

Work done by Radha in 3 days

Solution -

Let, total work  is 1

Radha completes a work in 15 days

Write it as,

The work done by Radha in one day =$\frac{total \:work}{Work\:complete \:in \:days}$

The work done by Radha in one day = $\frac{1}{15}$

The work done by Radha in 3 days = $The\: work \:done\: by\: Radha\: in\: one\: day \times 3$

The work done by Radha in 3 days = $\frac{1}{15}\times 3$

The work done by Radha in 3 days = $\frac{3}{15}$

Divide 15 by 3 we get

The work done by Radha in 3 day = $\frac{1}{5}$

∴ The work done by Radha in 3 days is 1/5 work .

Means Radha complete 1/5th work of total work in 3 days.

Answer 2

In context to question asked,

We have to determine the total unit of work done by Radha in 3 days.

As per question,

Radha completes the work in 15 days.

So, we can say that,

For determining the unit of work completed in 1 days we will divide the total unit of work by total number of days taken to complete the work.

So, we will get 1 day work as,

$=\frac{1}{15}\:unit$

So, for determining the total work done in 3 days we will multiply 3 by unit work.

So, total unit of work done in 3 days will be $=\frac{1}{15} \times 3 = \frac{3}{15} = \frac{1}{5}\:unit$

Hence, Radha will do $\frac{1}{5}$ of total work in 3 days.
