Question

If60% of 1250 are girlshow many are boys

Answer 1

Answer:

500 boys

Step-by-step explanation:

If 60% of 1250 students are girls

Then, total percentage of students= 100%

Percentage of girls= 60%

Percentage of boys= (100-60)%

                               =40%

So,

If there are 100 students, then no of boys will be 40

If there are 1250 students, then no. of boys will be (40/100*1250)

                                                                                   =500 boys

Answer 2

$60\% \: of \: 1250 = number \: of \: girls \\ then \\ \: \: \: \: \: \: \: \: = number \: of \: girls = \frac{1250 \times 60}{100} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{75000}{100}$
Two zeros are gets cancelled. Then we got
$\frac{75000}{100} = 750$
Now,
$number \: of \: boys = total \: number \: of \: students - number \: of \: girls \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 1250 - 750 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 500$
Hence, Number of boys is 500.
