Please help me? I really need the answer.

20

Step-by-step explanation:

Let the number of people be x.

Rs. 1000 is distributed equally among x people, so each person gets 1000/x.

If there were 5 people more, there would be x + 5 people.

Then, each person would get 1000/(x + 5). Each of the x + 5 people would get Rs. 10 less than before.

1000/x - 10 = 1000/(x + 5)

Multiply both sides by the LCD, x(x + 5).

x(x + 5) × 1000/x - x(x + 5) × 10 = x(x + 5) × 1000/(x + 5)

(x + 5) × 1000 - (x² + 5x) × 10 = x × 1000

1000x + 5000 - 10x² - 50x = 1000x

5000 - 10x² - 50x = 0

10x² + 50x - 5000 = 0

x² + 5x - 500 = 0

(x + 25)(x - 20) = 0

x + 25 = 0  or  x - 20 = 0

x = -25 or x = 20

The actual number of people is 20.

Check:

Rs. 1000/20 = Rs. 50

Rs. 1000 divided equally among 20 people gives Rs. 50 per person.

If there are 5 people more, then there are 25 people.

Rs. 1000/25 = Rs. 40

Rs. 1000 divided by 25 people gives Rs. 40 per person which is Rs. 10 less per person.

Our solution is correct.
