Biologists collected a random sample of 850 fish and 25 of them had been previously tagged. 850 : 25 = 34. It means that about 1/34 of all the fishes in the lake had been tagged. Therefore 600 * 34 = 20,400.
Answer: Based on this experiment, in the lake lives 20,400 fishes.

BaLLatris [955]

Answer:

The correct answer would be option C.

Explanation:

If there is a new co worker hired in my office, and its her beginning days, and I, along with other team members see that she is not as productive as other members of the team are, and we all have to work more and harder to make up for her work. So i would preferably give her advice and tips for how to get things done correctly and efficiently. I would not like to get her out of the office, rather i will try to make her understand the things as soon as possible and give her tips to increase her work efficiency. But if the problem continues, and I believe that she will not be able to cope up with us, then i will talk to the supervisor and suggest him that she might not be the best role for us. But i will go with option C.

Snowcat [4.5K]

Answer:

amount invest in B is 2000

Explanation:

given data

invested in Fund A = 5000

return profit A = 3%

return profit B = 10%

both together returned profit =  5%

solution

we consider here amount invest in B = x

so profit from fund B is

profit from fund B =  10% ×  x = 0.1 x

and

profit from fund A = 5000 × 3% = 150

so total profit = 0.1x + 150

and total profit = 5%

so we can say

5%  = \frac{0.1x+150}{5000+x}

solve it we get

x = 2000

so amount invest in B is 2000
