Question: x+y = ?
Statement 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.
40 < 6x < 50
i.e. 6.66 < x < 8.33
20 < 4y < 30
i.e. 5 < y < 7.5
NOT SUFFICIENT
Statement 2: x and y are distinct integers
NOT SUFFICIENT
Combining the two statements
x = {7, 8}
y = {6, 7}
But since x and y are distinct therefore
x = 8
y = 6
i.e. x+y = 14
OR
x = 8
y = 7
i.e. x+y = 15
OR
x = 7
y = 6
i.e. x+y = 13 hence
NOT SUFFICIENT
