Question

In a class there are 50 students. Number of girls 2 more than half the number of boys. Find the number of girls and boys in the class

Answer 1

Step-by-step explanation:

let the number of boys be X and the number of girls be y

then the total number of students= X+Y=50 .1

1/2x+2=y

1/2x-y= -2

x-2y=-4 .2

subtracting 1 from 2 we get

3y=54

y=18

and x=32

Answer 2

Answer:

above is your answer

hope it helps you thanks

Step-by-step explanation:

let number of boys be a and girls b

a+b=50 given

b=a/2+2 given

2b=a+4 ,b=(a+4)/2 ........(1)

a+(a+4)/2=50 putting value of (1)

2a+a+4=100

3a=100-4=96

a=32

so boys are 32 and girls are 18 [b=(32+4)/2]
