Question

10 students of class X took part in a mathematics quiz.if the number of girls is 4 more than the number of boys then find the number of boys and number of girls who took part in a quiz ​

Answer 1

Step-by-step explanation:

Let the number of boys = x

Number of girls = 4 more than the number of boys =x+4.

Given,

Total students participated in quiz = 10

Number of boys + Number of girls = 10

x+x+4= 10

2x +4= 10

2x = 10-4

2x = 6

x= 6/2

x= 3

therefore, number of boys = x= 3

Number of girls = x+4

= 3+4

=7.
