Answer:
the 2nd one. I got it correct
Step-by-step explanation:
Answer:
48 students.
Step-by-step explanation:
25% of total students = 12
suppose,
total students= x
so,
25% of x=12
(25/100)*x=12
25*x=(12*100)
x=1200/25
x=48
therefore,
x= total students= 48.

What is a linear equation in math?
- A linear equation only has one or two variables.
- No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
- When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
Suppose, time taken by faster maid be x , hours.
So, time taken by slower maid ,
( 4 time faster maid )
Now, time taken by both of the made together is given by ,



which is the time required by faster maid.
