number of girls =60x45/100=6x45/10=27 boys

number of boys=total students-number of boys

60-27=33 boys

therefore girls percentage is 45% and boys percentage is 15%

Answer 2

Answer:

The number of boys 33 .

Step-by-step explanation:

Given:

Total number of students = 60

Girls = 45%

So,

Number of boys = Total no. of students × % of boys / 100

$\sf \: Number \: of \: boys = \dfrac{55}{100} \times 60 \\ \\ \sf \implies \: Number \: of \: boys \: = \: \dfrac{3300}{100} \\ \\ \sf \implies \: Number \: of \: boys \: = \:33$
