Question

Visitors to a show were charged Rs. 15.00 each on the first day, Rs. 7.50 on the second, Rs. 2.50 on the third day. Visitors' total attendance for three days were in the ratio 2:5:13. Find out the average charge per visitor for the entire show.

• A. Rs. 7
• B. Rs. 5
• C. Rs. 9
• D. Rs. 11
• E. None of these

Answer 1

The correct option is B Rs. 5

Let attendance on first, second and third day be 2, 5 and 13, respectively.
Total number of visitors for three days = 2 +5 +13=20
Total amount of money collected
$=2\times 15+5\times 7.50+13\times 2.50$
$=30+37.5+32.5=100$
Average charge per person $=\frac{100}{20}=5$
