Hi mathsguru and others,


Thousand thanks to all that had answered my questions.

Another question:

1. The movie tickets sold on Thursday were 2/3 of the tickets sold on Friday. The tickets sold on Friday were 3/5 of the tickets sold on Satursday. If there were 380 movies tickets sold altogether. How many more tickets were sold on Satursday than on Thursday. :oops:

Thanksss.

The movie tickets sold on Thursday were 2/3 of the tickets sold on Friday. The tickets sold on Friday were 3/5 of the tickets sold on Saturday. If there were 380 movies tickets sold altogether. How many more tickets were sold on Saturday than on Thursday.

T: [][]

F: [][][]
S: [][][][][]

Total = 10 units = 380
Difference between Saturday and Thursday = (5-2) units = 3 units = 380/10x3=114
There were 114 more tickets sold on Saturday than on Thursday.

Hope this helps while waiting for http://www.kiasuparents.com/kiasu/forum/viewtopic.php?t=6311 model solution.

you all are thumb UP!!!.

Sorry, One more question.

1. During an IT fair, for each book sold, Leena received a commission of $20. An additional bonus of $10 would be given to her for every 5 books sold.

a) How much would Leena receive if she sold a total of 12 books?
My ans:
1 book = $20
5 books = ($20x5) + $10= $110

15 books = 15 /5 = 3 of 5 books
= 3 x $110
= $330

b) How many books had she sold if she was given $8880?
??? help.

Is my Qa correct ?

a) How much would Leena receive if she sold a total of 15 books?
b) How many books had she sold if she was given $8880?

(a)
15 books = (5+5+5) books
Total amount received by Leena if she sold 15 books = 3(20x5+10) = $330

(b)
1 'set' =($20x5)+$10 = $110
$8880÷$110 = 80 r $80

$80÷$20= 4

Total number of books = 80(5)+4 = 400+4 = 404
If she was given $8880, she had to sell 404 books
