Let water = W and cola = C.
We need to find W − C.
(1) 2W + 5C = 40
This is only ONE equation with TWO unknowns (W and C).
So we cannot find the exact difference.
(1) is NOT sufficient.
(2) 6W + 15C = 120
Divide by 3:
2W + 5C = 40
This is exactly the same equation as (1).
So we still cannot determine W − C.
(2) is NOT sufficient.
Answer: E, Neither statement alone nor both statements together are sufficient.

stmt 1.
2b + 3c = 40
many values fo (b,c) are possible like (12, 2) , (6,6) etc
stmy 2
6b+ 15 c =120
2b + 5 c = 40
values (b,c) are possible
stmt 1+ 2
no unique value ( b,c) can be derived
option E is looking fine here.

The cost of each bottle of water is the same and the cost of each bottle of cola is the same. What is the difference in the cost of 1 bottle of water and 1 bottle of cola?
(1) 2 bottles of water and 5 bottles of cola cost $40
(2) 6 bottles of water and 15 bottles of cola cost $120
As per statement 1
let the water price be x
let be cola price be y
2x+3y=40
here x and y can have various value
Hence not sufficient
As per statement 2
6 bottles of water and 15 bottles of cola cost $120
6x+15Y=120
it is same as statement 1 if we divide by 3
2X+5Y=40
here also x and y can have various value
Even combininf statement we cannot get unique value
Option E is correct neither statement is sufficient
