-Chetan K
number sof student of the group is 50
Step-by-step explanation:
let the number students be x
total bill is Rs 200
each student will pay =200/x
now 10 students do not have the money
so x - 10 students will pay the bill of Rs 200
according to the problem
= 
+ 1
or, - = 1
or, 200 ( 
- 
) = 1
or, 200(
) = 1
or, 200 X 10 = x(x-10)
or, 
- 10x - 2000 = 0
or, - 50x +40x - 2000 =0( using middle term factor)
or, (x - 50) (x+40) = 0
x = 50 ( x = -40 for number of students it is not possible)
the ratio of the volumes is 1728/27
take the cube root of the ratio
(1728/27) ^ (1/3)
1728^(1/3) / 27^ (1/3)
12/3
4/1
The ratio of the larger to smaller is 4/1

Answer:
20 or 40 or 50
(there are many others)
Step-by-step explanation:
A counterexample is an example that shows the statement is not true. The statement in this question is that if a number is a multiple of 10 (10, 20, 30, 40, 50, 60...) then it is a multiple of 30. Some numbers are, like 60 and 90, but not all numbers. So for example (counterexample) 20 is a multiple of 10 but NOT a multiple of 30.
40 is a multiple of 10, but NOT a multople of 30.
50 is a multiple of 10, but NOT a multiple of 30.
