6(x+9) is the factored expression.
There are 81 girls to every 72 boys in total, which can be represented by 81/72, which put into decimal form, is 1.125. If you then take the number of boys in the group, 16, and multiply it by this number (because the problem states that the ratio is constant) you can find the number of girls in the group.
16*1.125=18
So there are 18 girls in a group with 16 boys.

Answer:
10rupee notes are 11
20rupee notes are 22
Step-by-step explanation:
Let 10-rupee note be x
20-rupee note will be x + 11
The equation will be
10x + 20(x + 11) = 550
10x + 20x + 220 = 550
30x = 330
x = 330/30 = 11 = 10rupee notes
y = 11+11 = 22 = 20rupee notes
