Question

in an examination 45% of the total number of candidates were under 15 years of age of these 65% were boys and there were 441 girls find the total number of candidates​

Answer 1

Answer:

2800

Step-by-step explanation:

Number of Boys less than 15 years = 65%

Total Number of Girls less than 15 years = 441 = 35%

Total number of students less than 15 years = 441 / 35% = 441/0.35 = 1260

Total number of students less than 15 years = 45% = 1260

Thus, total number of students = 1260 / 45% = 1260 / 0.45 = 2800

Answer 2

Answer:

The total number of candidates in an examination room is equal to 2800.

Step-by-step explanation:

Given: the percentage of boys under the age of 15 $=65$%

So, the percentage of girls under age of 15 $=100-65=35$%

It means 441 girls are 35% of total number of candidates under the age of 15.

∴ The total number of candidates under age of 15 $=\frac{441}{35}*100 =1260$

Now, 1260 candidates are the 45% of total candidates in the examination room.

So, total number of candidates in the examination room will be:

Total number of candidates in an examination room  $=\frac{1260}{45}*100$

                                                                                        $=2800$ candidates
