Out of the total number of visitors on Saturday, 35% were adults. The cost for 1 adult’s ticket is double that for one child’s ticket. If the total amount collected from selling tickets on Saturday was Rs.8100. What is the cost of 1 adult’s ticket?

Options

A. Rs.200
B. Rs.160
C. Rs.120
D. Rs.100

Answer

D

Explanation

Let cost of 1 adult’s ticket = Rs. 2x, then
cost of 1 child’s ticket = Rs. x
According to question
(35% of 120) `xx` 2x + (65% of 120) `xx` = 8100
`rArr` 84x + 78x = 8100
`rArr` x = 8100/162 = 50
Hence, cost of 1 adult’s ticket = Rs. 2x = 2 `xx` Rs. 50 = Rs.100.
