Question

In a class there are 60 students. Out of which 15% are girls. The monthly fee of each girl is Rs

250 and fee of each boy is 34% more than the fee of each girl. What is total monthly fee of all

the boys and girls together?​

Answer 1

Answer:

$\bold\red{Rs.\:19,335}$

Step-by-step explanation:

Given,

Total number of students = 60

Also,

No. of Girls, G = 15% of 60

$=>G=\frac{15×60}{100}$

=> G = 9

Therefore,

No. of boys, B = 60-9

=> B = 51

Now,

It is Given that,

Monthly fee of each girls is ₹ 250

=> Total monthly fee,

for girls = ₹(9×250) = ₹ 2250

Also, it is given that,

fee for each boy is 34% more than that of girl

=> fee for each boy = ₹(250 + 34% of 250)

=> fee for each boy = ₹(250 + 85)

=> fee for each boy = ₹ 335

Therefore,

Total monthly fee,

for boys = ₹ (51×335) = ₹ 17,085

Thus,

Total monthly fee,

for all students = ₹ (2250+17085) = ₹19,335

Hence,

fee of all the boys and girls altogether is

₹ 19,335
