In a group of 15 children the ratio of the boy : the girl is 2: 3: 5 more girls join the group. Calculate the percentage of boys

marta [7]

Answer:

Percentage of new group boys = 30%

Percentage decrease for the boys = 10%

Increase percent of the girls = 10%

Step-by-step explanation:

Given:

Number of children = 15

Ratio (Boys to Girls) = 2 : 3

Number of more girls join = 5

Find:

Percentage of boys in new group

Percentage decrease for the boys

Increase percent of the girls

Computation:

Number of boys = 15[2/5]

Number of boys = 6

Number of girls = 15[3/5]

Number of girls = 9

Percentage of boys = [6 / 15]100

Percentage of boys = 40%

Percentage of girls = [9 / 15]100

Percentage of girls = 60%

New number of students = 15 + 5

New number of students = 20

New number of boys = 6

New number of girls = 9 + 5 = 14

Percentage of new group boys = [6 / 20]100

Percentage of new group boys = 30%

Percentage of new group girls = [14 / 20]100

Percentage of new group girls = 70%

Percentage decrease for the boys = 40% - 30%

Percentage decrease for the boys = 10%

Increase percent of the girls = 70% - 60%

Increase percent of the girls = 10%

Write a function rule for the table.

Pavlova-9 [17]

The correct answer is: [C]: " p = 6.25 h " .
______________________________________________________
Explanation:
______________________________________________________

It is clear that "pay" is a function of "hours worked" ;

So, we can eliminate: "Choice [B]: " h = 6.25p" .
______________________________________________________
Try, Choice [A]: " p = h + 12.5 " ; and 14.50 ≠ 12.50 ; (12.50 is the amount shown in the table. So, we can already eliminate "Choice [A]".
_____________________________________________
Now that we have eliminated choices [A] and [B];

we are left with choices: [C] and [D]:
_____________________________________________
Consider choice [C]: " p = 6.25h " ;
 when "h = 2" ; does: "p = 12.5" (as shown on table)?? ;

i.e. " 12.5 =? 6.25 * (2) ?? Yes! This choice is a POSSIBILITY.
_____________________________________________
Consider choice [D]: " p = 12.5h" .

When "h = 2, does "p = 12.5" (as shown on table)? No!
→ We can see from this very answer choice
(the equation itself) that when "h = 2" ;
the value of "p" is DOUBLE [that of "12.5"].
________________________________________________
The correct answer is: Answer choice: [C]: " p = 6.25 h " .
