if solution (x) with alcohol (14%) and solution (y) with alcohol %(20%) mixed together to form 24 liters of mixture .then the amount of solution(x) is?
a) the alcohol in solution(mixture) is 15%
b)if we enter changed the amounts of solutions 'x' and 'y' we get mixture of alcohol %,44%

-
- only (a) is necessary to answer the question.
because (b) is practically impossible, u can never get 44% by mixing these two together.
(as simple as that) ;) - 9 years agoHelpfull: Yes(13) No(1)
- Either a or b.
x + y = 24
14% of x + 20% of y = 15% of 24 - 9 years agoHelpfull: Yes(5) No(4)
- statement itself is sufficient
no need of a or b - 9 years agoHelpfull: Yes(1) No(4)
- x^2-x-3=0
so 2 solution - 9 years agoHelpfull: Yes(0) No(3)
- how can u say that either a or b.....if a+b=24
it can be either 12+12=24
or like......16+8=24 can take any combo
so acc to me neither is sufficient

- Though we can make equations using either of the statements; But upon solving either of these equations, the answer is hypothetical. either 'X' or 'Y' comes negative which can't be true.
Hence: Data Insufficient - 9 years agoHelpfull: Yes(0) No(2)
- Correct option is: A
Statement 1 is sufficient to answer this question.
Statement 2 cannot be used . - 7 years agoHelpfull: Yes(0) No(0)
