A. at least 30
B. at most 20
C. exactly 25
D. exactly 50

Answer 1

The number of newspapers can be calculated by dividing the total number of newspaper readings (350 students × 6 newspapers each) by the number of students who read each newspaper (70), which results in at least 30 newspapers.

Step-by-step explanation:

Given that every student in a college of 350 students reads 6 newspapers and every newspaper is read by 70 students, we can find the number of newspapers by setting up a ratio. Since each newspaper is read by 70 students, we can divide the total number of newspaper readings (the product of the number of students and the number of newspapers each reads) by the number of students who read each newspaper.

Here is how we calculate it:

1. Total number of newspaper readings = Number of students × Number of newspapers per student = 350 × 6.
2. To find the number of newspapers, we divide the total number of newspaper readings by the number of students per newspaper: (350 × 6) / 70.
3. This simplifies to (350 / 70) × 6, which is 5 × 6 = 30.

Therefore, the number of newspapers may be equal to at least 30.
