hi, my answer is B but the answer given was actually D...
An equilibirum can be represented by the following equation.
P(aq) + Q(aq) <=> 2R(aq) + S(aq)
In a certain mixture, the equilibirum concentration of Q is 10 moldm^-3.
What will be the new equilibirum concentration of Q if 5 mol of pure Q is dissolved in the mixture?
A. 15moldm^-3
B. between 10moldm^-3 and 15moldm^-3
C. 10moldm^-3
D. between 5moldm^-3 and 10 moldm^-3
thank you very much! ^^

Your own answer of "between 10moldm^-3 and 15moldm^-3" is the correct one. The only way for the answer to be "between 5moldm^-3 and 10 moldm^-3", is to either remove some of Q or R or S (but not P), or increase the volume of the container such that all molarities are decreased.
