Hi concerned1970,

Hope this helps and my solution may be the ideal one..


Given:
Children: $2 Adult: $5
The ratio of children to adults is 2 : 1
The price for 2 children and 1 adult is $9 (1 group)

Total amount of money collected / 9 ----> 1080 / 9 = 120 groups

This means there are 240 children and 120 adults.

Ans : There were 120 adults at the concert.


Check back : 240 x 2 + 120 x 5 ---> 480 + 600 = 1080

1 unit for adults: 5x
\" \" \" children: 2x

2x X 2 = 4x
4x + 5x = 9x
1080/9 = 120

Hi ttyh

It is suggested that you draw a MD.

Benny ----- 7 units
Muthu ------ 1 unit

6 units -------20+25 -----45
1 unit ------7.5

Benny -------52.50

Hello Uncles and Aunties, can you please help me with this question? Thank you.



Siti and Mohan started counting at the same time. Siti counted on by hundreds from 2000. Mohan counted backwards by thousands. After 4 counts, they had reached the same number. What number did Mohan start counting from?

Hope this helps.

3 files and 2 books cost $60 --------(1)
2 files and 3 books cost $70 -------(2)

So:
5 files and 5 books cost $130
1 file and 1 book cost $26
2 files and 2 books cost $52 -------(3)


From (1):

3 files and 2 books = 1 file + 2 files and 2 books
$60 = 1 file + $52
1 file = $8

1file cost $8

Hi Blur Baby, aunty vlim hereby try to help you since tianzhu not around now..

After 4 counts, Siti would be : 2000, 2100,2200, 2300
Since both reached the same number after 4 counts, so Mohan would be 2300 after counting backwards by thousands after 4 counts
2300, 3300, 4300,5300

so Mohan start counting from 5300.

Hope u understand my explanation
