in a class there are 60 students out of which 15% are girls the monthly fee of each girl is rupees 250 and fee of each boys 34% more than the fee of each girl what is total monthly fees of all the boys and girls together

Answer 1

In class there are 60 students -15 percent of girls
1 girl -250
girls in class-15/100*60=15*6/10
Then boys in class-34%+15%=59%
59/100*60=59*6/1005005000
15*6/10*250 (this is girl total monthly fees)
59*6/10*250 (this is boys total monthly fees)

Answer 2

Number of total students in a class is 60
No. of girls= 15% of 60
=
$\frac{15}{100} \times 60 = 9$
Number of boys =60-9=51
Monthly fee for each girl=250rs
For 9 girls =9×250=2250
Monthly fee for boys is 34% more that girls
$250 + \frac{34 \times 250}{100} = 335 \: rs$
Monthly fee for each boy =335
for 51 boys=335×51=17085
Total fees =17085+2250=Rs 19335
