What is the value of x + y?
(1) When x is multiplied by 6, the result is between 40 and 50, and when y is multiplied by 4 the result is between 20 and 30.
(2) x and y are distinct integers.
1) x = \(\frac{41}{6}\) or 7...
y = \(\frac{21}{4}\) or 6...
Insufficient.
2) Insufficient. We don't know the values of x and y.
1+2)
Here is why this question is poorly worded. It's not clear if the numbers are between 40 and 50, inclusive, or exclusive.
If it's inclusive then.
x = 7 or 8
y = 5,6 or 7
x + y = 13 or 14.
Insufficient. Answer is E.
If it's excluding 40, and 50, and 20, and 30 then,
x = 7 or 8
y = 6 or 7
x + y = 14
Sufficient. Answer is C.
Can you please check this question? Unless I'm missing something.
