Answer 1

Answer:

The share to be received by assistant is Rs. 300

Step-by-step explanation:

Given : A alone can do a piece of work of Rs800 in 8days. But by engaging an assistant ,the work is completed in 5 days.

To find :The share to be received the assistant.

Solution :

Let work done by A is in 8 days

But engaging an assistant (B) work done is in A+B= 5 days

Which means B can do work alone in 8-5=3 days

Alone can do a piece of work in 8 days  and get = Rs 800

For 1 days = $\frac{800}{8}=100$ Rs

For 3 days i.e, assistant can get = $100\times 3=300$ Rs

So, The share to be received by assistant is Rs. 300

Answer 2

Answer: The assistant receives a 37.5 % (₹ 300) share.

Step-by-step explanation:

It is given A alone does the work in 8 days for ₹ 800.

So, per day he gets = 800/8 = ₹100

Now, when the assistant joined, the work finished in 5 days.

Thus, the money A will receive = ₹ 100 x 5 = ₹ 500

The assistant will receive the remaining amount = ₹ 800 - ₹500 = ₹300

So, percentage share of assistant = (300/800)$\times$100 = 37.5%
