here is your answer ☞
________

Given: Number of students in class = 48

Let the number of boys in class = x

Then number of girls in class = (48 - x)

According to the question

3x/4 + 2(48 - x)/7 = 23

⇒ 3x/4 + (96 - 2x)/7= 23

⇒ 21x + 384 -8x = 23×28

⇒ 13x = 644-384 = 260

⇒ x = 20

Hence,

number of boys in class = 20____answer

and

number of girls coming to school by bus
= 2(48 - 20)/7 = 8. ____answer

hope it will help you
