Hi MathIzzzFun,


Hi MathIzzzFun
Thanks for the prompt reply for the below question: But I need to ask you why we need to do this step. The rest I understand.

$12 ticket sales / $30 ticket sales = 5/12

At a concert, tickets were sold at $12, $30 and $50. The sales of $12 tickets made up 25% of the total amount of money collected. The sales of $30 tickets made up 60% of the total amount of money collected. Given that 15 more $12 tickets were sold than the $30 tickets, how many $50 tickets were sold?
Thanks


$12 ticket sales / $30 ticket sales = 5/12
number of $12 tickets x $12 = 5/12 x number of $30 tickets x $30
number of $12 tickets = 5 x 30 /(12 x 12 ) x number of $30 tickets
number of $12 tickets = 25/24 x number of $30 tickets

number of $12 tickets --> 25u
number of $30 tickets --> 24u
15 more $12 tickets were sold than $30 tickets
1u --> 15

$12 ticket sales = 15 x 25 x $12 = $4500
$50 ticket sales = $4500 ÷ 5 x 3 = $2700

number of $50 tickets sold = $2700/$50 = 54

Hi

Pls check this out.

No of $ 12 Tickets: --> 1U+15
No of $30 Tickets: -> 1U

Total Amount Collected Sale of $12 Tickets = > $12(1U+15) = 25%
Total Amount Collected Sale of $30 Tickets = > $30(1U) = 60%
Total Amount Collected Sale of $50 Tickets = (100 -85) = 15%
12U + $180 = 25 %
30U = 60%
1 U = 2%
12 (2%) + $180 = 25%
180 = 25% -24%
1% = 180
Total Amount Collected Sale of $50 Tickets = (100 -85) = 15%
15 X 180 = 2700
No tickets = 2700/50 = 54

a gym club had 180 members last year. the number of girls decreased by 30% and the number of boys increased by 40%. there were now as many girls as boys.


was there an increase or decrease in membership this year?
how many more or fewer this yr?

Hi Icon

At the beginning 100% of Girls + 100% of boys = 180
Girls decreased by 30% and boys increased by 40%
At the end 70% of Girls (100-30) = 140% of boys ( 100+40)
1% of the girls = 2% of the boys
At the beginning 100% of the girls = 200% of the boys
300% --> 180 100% of boys = 60
At the end Total 280% of boys (70% of the girls = 140% of the boys)

Ans: was there an increase or decrease in membership this year? -Decreased

Ans: How many more or fewer this yr? - 20% fewer this year
\t300% --> 180 20% represent 180/300 x 20 = 12 members

Hi sptamila
Shouldn’t the no of boys who painted chairs be 90/20 x2. How to arrive at the boys to be 10 ?[/quote]Sorry, I calculated total number of boys. Total no of boys painted chairs should be 90/20 x2 = 9 or 45 x 20%

Need some guide. 3/4 of john's age is equal to twice of May's age.what is the ratio of john's age to Mary's age?

Hi,

3/4 of john's age => twice of May's age

3/4 of john's age = 3 x 2 - 6 years
Mays age = 6/2v= 3 years
John's age = 6 x 4 /3 = 8 years

Ratio 8: 3
