we have two equations to solve the problem:
50x+72y=92600
y-x=100
solving for x gives us 700, so the answer is A
we can consider picking but for me it is better to solve equations than put one or two answer choice
Thanks. This line created confusion for me. Can you elaborate as to how the two equations were formed?
Does it mean that every registered person had the Lunch? Also Lunch was attended by other non-registered persons.
If the number of registrants who paid for lunch was 100 more than the number who did not,Hello PareshGmat.
Hope this might be useful to you.
Let the number of people who have opted only to register = x
Now since the registration cost is 50$ per person, the total amount sums to = 50x $
As per the information given in the question, the number of registrants who paid for lunch was 100 more than the number who did not. That means, total number of people who registered and paid for lunch = 100 + x.
For the people who registered for lunch the cost is 50 $ (for the event registration) + 22 $ (for lunch) = 72 $.
Total amount in this case sums to = 72(100 + x) = 7200 + 72x
Now, total amount received was 92,600.
Thus, from the above data,
50x + 7200 + 72x = 92600
122x = 92600 - 7200
122x = 85400
x = 700.
Hence the correct Ans is
