Answer:

The population of 75 hours from now would be 40,000.

Step-by-step explanation:

The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.

<h2>~<u>Solution</u> :-</h2>

Here, it is given that the bag contains 25 paise coins and 50 paise coins in which, 25 paise coins are 6 times than that of 50 paise coins. Also, the total money in the bag is Rs. 6.

Hence, we can see that, here, we have been given the linear equation be;

Let the number of coins of 50 paise will be $ x $ and the number of coins of 25 paise will be $ 6x $ as given. . .

Hence,

$x + 6x = 6$

$7x = 6$

$x = \frac{6}{7} \\$

$x = 1.1666667 \approx \: 2$

Hence, the number of 50 paise coins will be <u>2</u>. And, 6 times of two be;

$6(2)$

Hence, the number of 25 paise coins will be <u>12</u>.

SO WE GET -14X^2+9X.

X(-14X+9)= -14X(*)X+9(*)X= -14X^2+9X
