Did anyone else find STAV 2010's solutions dodgy?

I was just wondering if anyone else has done STAV 2010? Is it just me or was Q.7's solution inaccurate? It asked for the percentage yield. We had to calculate the theoretical mass (0.273g) and the mass obtained was given (0.268g). I thought the answer was 0.268/0.273X100=98.2% but the solutions said it was 0.273/0.268X100=102%, is there a reason or..?


Thanks :)
