Answer 1

Answer:

Step-by-step explanation:

Define x:

Let one of the number be x

The other number is 3x

Solve x:

The product of the two numbers is 18.75

x(3x) = 18.75

3x² = 18.75

x² = 6.25

x = √6.25

x = 2.5

Find the numbers:

one of the number = x = 2.5

the other number is 3x = 3(2.5) = 7.5

Answer: The greater number is 7.5

2) Let's assume that there were x number of students present in the school

Now according to the question

x*x=230400

x²=230400

x=√230400

x=480 paisa = Rs4.8

So, each sudent paid Rs 4.8 and there were 480 number of students.
