Question

10 students of class 10 took part in mathematics quiz if the number of girl is 4 more than number of Boy's find number of boys and girls

Answer 1

x= boys
x+4= girls

APQ: x+x+4=10
2x+4=10
2x=6
x=3
hence no. of boys=3
that of girls = 3+4=7

Answer 2

Hey Friend

Suppose number of boys = x

Number of girls        = y

Given that total number of student  is 10 so that

x + y    = 10

Subtract y both side we get

x          = 10 – y

Plug y = 0 , 5, 10 we get

x         = 10 – 0          = 10

x         = 10 – 5          = 5

x         = 10 – 10        = 0


X=10,5

Y=0,5


Given that If the number of girls is 4 more than the number of boys

So that

y          =  x + 4

Plug x = -4, 0, 4, and we get

Y         =  - 4 + 4         = 0

Y         =  0 + 4           = 4

Y         =  4 + 4           = 8

X=-4,0,4

y=0,4,8


So number of boys = 3 and number of girls = 7
