dybincka [34]

Answer:

<h3><u>Solution</u><u>:</u><u>-</u></h3>

Let

Tinky's age=x

Laa's age=x+2

According to the question

$\qquad\quad {:}\longmapsto\sf 5 (x+x+2)-1=x (x+2)$

$\qquad\quad {:}\longmapsto\sf 5(2x+2)-1=x^2+2x$

$\qquad\quad {:}\longmapsto\sf 10x+5-1=x^2+2x$

$\qquad\quad {:}\longmapsto\sf 10x+4=x^2+2x$

$\qquad\quad {:}\longmapsto\sf 10x-2x+4=x^2$

$\qquad\quad {:}\longmapsto\sf x^2=8x+4$

$\qquad\quad {:}\longmapsto\sf x^2-8x-4=0$

alexgriva [62]

Answer: room 101 and room 107

Step-by-step explanation:

In room 101, the ratio of boys to girls is 16:12. This is further simplified to its lowest fraction by dividing by 4. It becomes 4:3

In room 104, the ratio of boys to girls is 20:9. This cannot be further simplified to its lowest fraction.

In room 107, the ratio of boys to girls is 12:9. This is further simplified to its lowest fraction by dividing by 3. It becomes 4:3

Therefore, room 101 and room 107 have the same ratio.
