Answer 1

15 Is to 16 is the answer for the question

Answer 2

Answer:

4 : 3

Step-by-step explanation:

Given,

20 girls can do a dance performance after practicing for 16 days,

That is, 20 girl's one day work = $\frac{1}{16}$

⇒ 1 girl's one day work = $\frac{1}{320}$

Now, 16 boys can perform the same dance preparing for just 15 days,

That is, 16 boy's one day work = $\frac{1}{15}$

⇒ 1 boy's one day work = $\frac{1}{240}$

Ratio of capacity of a boy and a girl

= Boy's one day work : Girl's one day work

$=\frac{1}{240}:\frac{1}{320}$

= 4 : 3
