Question

The mean number of tickets sold daily by a comedy show over a seven-day period was $52$. The show sold $46$ tickets on the last day of that period. Find the mean number of tickets that were sold daily over the first six days.

• A. $53$
• B. $54$
• C. $55$
• D. $56$
• E. $57$

Answer 1

Answer: (A)

$53$

The total number of tickets sold on seven days is $52\times 7=364$
The tickets sold on last day are $46$.
Therefore the tickets sold on first six days is $364-46=318$
Therefore the mean of first six days is $\frac{318}{6}=53$
