We are given total 10 tree seedlings.
Number of workshops = 2.
Here order doesn't matters.
<em>When order doesn't matters we apply combination.</em>
We know formula of combination:
For the given situation, we have
n=10 and r=2.
Plugging values in formula, we get
X = the number of humans and y = the number of horses.
x+y=74
2x+4y=196
Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.
So, now that you have y, you can plug it into the first equation to find x:
So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.
