Answer 1

Step-by-step explanation:

$\sf\dag answer$

Total student =60

% of girls =45%

No. of boy =?

No. of girls =

$= 60 \times \frac{45}{100} = \frac{6 \times 45}{10} = 27girls$

=27 girls

No. of boys = Total students - No. of girls =60−27=33 boys

Answer 2

Answer:

Percentage of students absent =25

Number of students present =45

We know that total strength of students is equal to 25% absent+45 present =100%

So percentage of students present=100–25=75

Therefore total strength =45×100/75 =60.

Let me varify my answer,

25% absent=60×25/100 =15

Number of students present=45

Therefore total strength =15+45 =60.
