Question
The required staff to student ratio for an excursion is 2 : 15. If 10 teachers attend the excursion, what is the maximum number of students who can attend?
Hint:
Unitary method: The unitary method is a method in which we find the value of a unit and then the value of a required number of units. For example, If 10 apples cost is 100 rupees, 1 apple will cost 10 rupees and if we are asked to find the cost of 100 apples, we can find it by multiplying 100 with the cost of 1 apple.
The correct answer is: 75 students
The teachers to students for an excursion ratio is given as 2:15 or we can write
We are asked to determine the maximum number of students who can attend an excursion if 10 teachers attended the excursion.

= 
No. of students = 
= 75 students.
Final Answer:
