Let's set up a proportion to solve this problem.
The number of students who have arrived (70) is 35% of the total number of students in the group.
Let "x" represent the total number of students in the group.
We can write this proportion as:
70/x = 35/100
Now, we can solve for "x" by cross-multiplying:
35x = 70 * 100
35x = 7000
Dividing both sides of the equation by 35 gives us:
x = 200
Therefore, the total number of students in the group is 200.
Therefore, the correct answer is A200.
