Answer 2

Answer:

25

Step-by-step explanation:

HEY

LOOK ITS VERY EASY, JUST NEED TO USE OUR MINDS A LITTLE BIT

LET THE NO. OF BOYS =X

SO ACCORDING TO THE QUESTION

NO. OF GIRLS WILL BE 1/5X

THERE ARE TOTAL 30 STUDENTS IN THE CLASS  

NO. OF BOYS + NO. OF GIRLS =30

SO X+1/5X=30

MULTIPLY THE EQN BY 5

WE GET

5X+X=150

6X=150

X=150/6

X=25

SO THE NO. OF BOYS IN A CLASS = 25
