Hi Guru, this is concern_mum again, can you help me with question below:


There were 512 tickets to the YOG opening and closing ceremoney for sale. After 3/4 of the opening ceremony tickets were sold, the number of opening ceremony tickets left was 3/7 of the total number of tickets left.

a) How many closing ceremony tickets were there?
b) If the tickets were sold at $80 each, how much money was collected from the sales of the opening ceremony tickets?

Thank you.

Hi

There is no mention of sale of closing ceremony tickets...without this information, there will be more than 1 possible solution.

Assuming that no closing ceremony tickets were sold:
Opening tickets = 12u
Opening tickets left = 3u = 3/7 total remaining tickets--> remaining tickets = 7u
So, closing tickets = 4u

512 = 12u+4u = 16u
Closing tickets =4u = 1/4 x 512 = 128

after that, (b) is quite straightforward .

cheers.

Please help with these 2 questions,thanks.Any good way to explain question 1?


Thanks for your help.

1)Ms Tan has a bag of sweets to distribute to the pupils in her class.If she gives each pupil 5 sweets,she’ll have 3 sweets left.If she gives each pupil 7 sweets,she’ll need another 25 sweets.

1) How many pupils are there in her class?
2)How many sweets does she have in her bag?

2)A florist sold twice as many roses as tulips and collected $400 in total.She collected $80 more on the tulips than the roses.Given that a tulip costs $2 more than a rose,find the cost of a rose.

Hi

For Q1, there was a long discussion on a similar question - http://www.kiasuparents.com/kiasu/forum/viewtopic.php?f=67&t=25121&start=70

Q2. First, find how much was collected for Roses and Tulips.
Roses = $(400-80)/2 = $ 160
Tulips = $240

For 2nd part, there are few ways to do :
We know that the number of roses sold is twice the number of tulips sold.

If there were same number, then we could easily find out the number of each type sold by dividing the extra amount collected by the extra cost per tulip over rose.

So, we assume same number were sold ie 2 x $ 240 = $ 480 worth of tulips sold. So, $480 - $160 = $320. Since each tulip costs $2 more that a rose, then number of roses sold = $320 / $2 = 160, so number of tulips sold = 80

Cost of 1 rose = $160/160 = $1, cost of 1 tulip = $240/80 =$ 3

Alternatively,
we know that 2 lots of roses sold for $160 and 1 lot of tulips sold for $240
1 lot of roses sold for $160/2 = $80
Number of flowers in each lot = $(240-80)/$2 = 80
Cost of 1 rose = $160 / 160 = $1
Cost of 1 tulip = $ 240 / 80 = $3

Hi

both questions are similar..

1) Amount earned for every 15 boxes = $ 3 x 15 + $ 8=$53
220/15= 14 R10
Amount earned = 14 x $ 53 + 10 x $ 3=$772

2) For every 50 watches repaired, amount earned = $20 x 50 + $60=$1060
5560/1060= 5R260
Number of watches she must repair to earn $5560= 5 x 50 + $260/$20 = 263

cheers.

Hi, please help


Jolene and Penny had a sum of money. Jolene gave Penny 0.4 of her money. Penny then gave Jolene 1/2 of her money. In the end, Jolene had 3 times the amount of money that Penny had. If Jolene gave Penny $125 more that what Penny gave Jolene, how much money did Jolene have at first?

Thanks
