Back question 377 of 383 Next

Explanation

The correct answer is 184. It's given in the table that there are 375 objects in group A and 690 objects in group C. It’s also given that the number of objects in group C is p% of the number of objects in group A. Therefore, 690 is p% of 375, which can be represented by 690=p100375, or 690=3.75p. Dividing both sides of this equation by 3.75 yields 184=p. Therefore, the value of p is 184.
