Answer 1

The answer should be Rs. 48,000

Answer 2

Answer:

38400

Explanation:

Given,

The revenue in the month of March = 40,000,

Let x be the original number of sales,

So, the price of each good in march = $\frac{40000}{x}$

Now, after 20% off in April,

The price of each good in April = (100-20)% of $\frac{40000}{x}$

$=80%\text{ of } \frac{40000}{x}$

$=\frac{80\times 40000}{100x}$

$=\frac{32000}{x}$

Now, the number of goods in April  = 20% more than the original number of goods,

= (100+20)% of x

= 120% of x

$=\frac{120x}{100}$

$=1.2x$

Hence, the revenue in the month of April = number of goods × price of each good

$=1.2x\times \frac{32000}{x}$

= 38400
