Answer 1

Answer:

It's 25 boys.

Step-by-step explanation:

Ravi is the 16th. So there are 15 boys in-front of him. If you x2 that you get 30, so there are 30 boys behind Ravi. The fifth boy from the back, which means 30 - 5 = 25. There is your answer.

Answer 2

Given: Ravi is sixteenth from the first in a column of boys. There are twice as many behind him as there are in first.

To find: How many boys are there between ravi and fifth boy from the end of the column​.

Solution: There are 25 between Ravi and fifth boy from the end of the column​.

According to the question, Ravi is 16th in a column. This means that there are 15 boys in front of him. Also, there are twice as many behind him. This means that the number of boys behind him is

$15*2 = 30$

Thus, the total number of boys in the column is

$16 + 30 = 46$

So, the fifth boy from the end is in the 42nd position from the front. Thus, the number of boys between the 16th and 42nd positions can be calculated as shown below.

$42 - 16-1 = 25$

We subtract one because the 16th and the 42nd positions are not considered.

Therefore, there are 25 between Ravi and fifth boy from the end of the column​.
