Answer 1

In neelam class the ratio of boys and girls is2:3 neelam rank from bottom is 14th and 6th rank from girls if neelam rank is 32 then how many girls are there above from Neelam in the class (correct question)

Given:

ratio of boys and girls is 2:3.

neelam rank from bottom is 14th and 6th rank from girls.

neelam original rank is 32.

To Find:

Number of girls in Neelam class.

Solution:

1) If the original rank of the neelam is 32 then it is obvious that the rank must be from the begining of the ranking.

2) It is given in the question that the rank of the neelam is 14th from the bottom.

3) So the number of the students must be 32 + 14 - 1 = 45.

4) According to the ration there must be 3x girls in the class and the total student is 5x.

so,

• 5x = 45
• x = 45/5
• 3x = 9 × 3 = 27

The number of girls in the neelam class is 27.

Answer 2

Given :

Ratio of boys and girls in neelam's class = 2:3

Rank of neelam from bottom = 14

Rank of neelam from bottom in girls = 6

Total rank of neelam = 32

To find :

Number of girls above neelam's rank.

Solution :

Rank of neelam = 32

So 31 students are above neelam's rank.

Rank of neelam from bottom = 14

So 13 students are below neelam's rank.

So Total number of students = 31+13 +1 = 45 students

It is given that ratio of boys and girls = 2 : 3

So, if 2x are number of boys and 3x are girls then

$2x \: + 3x \: = 45 \\ \\ 5x = 45 \\ \\ x = \frac{45}{5} = 9$

So,

Number of boys =

$\bf 2\times x =18$

and

Number of girls =

$\bf 3\times x =27$

Neelam's rank is 6 from bottom (given)

So, out of 27 girls 5 girls are below her rank,

1 rank is hers

and remaining girls are above her.

So, Number of girls above Neelam's rank =

27 - 6 = 21
