she would first calculate how many drinks she sell the other weeks and know the rate at which each customer buy the drinks.
Let one of those numbers be x.
Now,
according to question,
The other number must be,
3x-6
Now,
as said in the question,
x+3x-6 =62
4x -6 =62
4x = 68
x = 17.
Now,
we got one of those numbers which was x = 17,
and the other number should be 3(17)-6 = 51-6 = 45.

Answer:
There are 26 students in the class
Step-by-step explanation:
Let n millilitres be the solution in the beaker
Let x be the number of students in a class
He gives 3 millilitres of solution to each student . He will have 5 millilitres left over.
So, Solution distributed = 3x
Remaining solution = n-3x
So, n-3x = 5 ----1
In order to give each student 4 millilitres of solution, he will need an additional 21 millilitres.
So, n-4x=-21 -----2
Substitute the value of n from 1 in 2
So, 5+3x-4x=-21
5-x=-21
26=x
Hence There are 26 students in the class
