8. Tommy Thomas's tankard holds $480 \mathrm{ml}$ when it is one quarter empty. How much does it hold when it is one quarter full?
A $120 \mathrm{ml}$
B $160 \mathrm{ml}$
C $240 \mathrm{ml}$
D $960 \mathrm{ml}$
E $1440 \mathrm{ml}$
Solution: B
When Tommy's tankard is one quarter empty it is three quarters full. So $480 \mathrm{ml}$ is three quarters of the capacity of the tankard. So when it is one quarter full it holds $\frac{1}{3}(480)=160 \mathrm{ml}$.
