time?​

Answer 1

Answer:

Step-by-step explanation:

Given,

16 experts can do as much as 28 trainees in a given time.

The ratio obtained here is:

$16 : 28$

= $4 : 7$

A piece of work can be done by 12 experts and 15 trainees.

If 4 experts can do as much as 7 trainees, 12 experts can do as much as 21 trainees.

The piece of work must be done by totally:

$21 + 15 = 36$  trainees

If 4 expert can do as much as 7 trainees, 8 experts can do as much as 14 trainees.

To complete the work:

$14 +$Amount of trainees= $36$

⇒ $14 + x = 36$

⇒ $x = 36 - 14$

⇒ $x = 22$

Thus, 22 trainees are needed alongside 8 experts
