Need some help with Math problem :/

2283 concert tickets were sold for a total of $17829.
If students paid $6 and nonstudents paid $9, how many student tickets were sold?

(i'm trying these after i type them and checking my answers with what you guys get )

 

15 and 30?

 

Number of tickets sold to students = x
Therefore non student tickets = 2283-x
Total collection = 6x + 9 (2283-x) = 17829
20547-3x = 17829
3x= 2718

x= 906

 

damn sachin are you still in school? i have not do any math problem in 2 year and i lost my ability to solve those problem

 

use the differences to find a pattern in the sequence..

8,9,19,43,86,153,249

Assuming that the pattern continues, the 8th term should be?

 

I guess 379

 

Edit
yeah it is 379.
make 2 pairs of differences between those numbers. That will get your answer as 379

 

you are correct!

 

I'll type out one's from last week, those are more logic ones but they were fun to figure out


1. You have to walk to a river to get water. How can you measure out exactly six gallons of water using only a 4 gallon container and a 9 gallon container?

2. A textbook is opened and the product of the page numbers of the two facing pages is 6162. What are the numbers of the pages?

3. On a balance scale, three die and four jacks balance 18 marbles. Also, one jack balances one die and one marble. How many marbles will balance one die?

4. In a very strange world, one giraffe weighs the same as two frogs, two ostriches weigh the same as one lion and three lions weight the same as one giraffe. How many ostriches does it take to weigh the same as one frog?

 

Q2---the page nos are 78 and 79
for q 3--2 marbles will balance one dice
for the question below that,3 ostriches will weigh the same as a frog

 

Yes, 344 is correct. Think of it as:

(147 + 198) - 1 = 344

Code (markup):

and yes this was hard...

 

-I got 7 marbles balance one dice

-I got 3 ostriches also

 

Right

3d+4j=18m
1j=1d+1m

Therefore

j=(1m+1d)


3d+ 4(m+d) = 18m

or

7d = 14m

 

1. Solve the following cryptarithm using only the numbers 0,1,2,3,6,7,and 9

sun
+ fun
swim


2. How can you use a 5 minute hourglass and an 8 minute hourglass to measure 1 minute?

3. Jim has four more brothers than sisters. How many more brothers than sisters does his sister Mary have?

4. How many squares are there on an 8x8 checkerboard?

5. A 6 foot by 10 foot rectangular lawn has a concrete walk 3 feet wide all around the outside of it. What is the area of the walk?

 

For text boox question , you will need a quadratic equation

x (x+1) = 6162

x(x) +x + 1 =6162

x(x) + x -6161 = 0

78,79 is the answer.

 

Can you explain how you got 2 marbles? I got 7 somehow...? I'm not sure if I'm right

 

Checkerboard has

8sq+7sq+6sq......+1sq = 64+49+36+25+16+9+4+1 = 204 squares.

(Difficult to explain , but you can see the pattern if you draw squares on paper.Start with 2x2 square, then draw 3x3 square... you will see how number of squares increase)

 

There are 100 lockers in a row and 100 students. The first student starts at locker 1 and opens all the lockers. The second student starts at locker 2 and opens or closes every other locker (locker 2,4..). The third student starts at locker 3 and opens or closes every third locker (locker 3,6..). This pattern continues for all 100 students.

1. After all students are done, which lockers are left open?
2. If we added another 100 students (lockers 101-200) which would be the next locker open?
3. Using the idea from #2 above (lockers 101-200) which would be the last locker open?

 

Six more brothers - including Jim , excluding Mary

 

Ok, if you believe the crap you kids are putting up is challenging, check this out:

Sequences/Series... (algorithms)

Give me the next three (3) terms to the sequence:
0.2, 81.022, 918.048, 71,872.12, ___, ___, ___ ...
