There are 52 students in a class, 14 boys are less than 13 girls. How many boys and girls are there?


Suppose there are x boys, & nbsp; & nbsp; & nbsp; 14x = 13 × (52-x) - 1, & nbsp; & nbsp; 14x = 523-13x-1, & nbsp; 14x + 13X = 493-13x + 13X, 712x △ 712 = 493 △ 712, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 28, 52-28 = 24; a: there are 28 boys and 24 girls



There are 42 students in a class of six years, and the number of girls is 4 / 3 of the number of boys. How many boys and girls are there?


There are 18 boys and 24 girls
Setting: the number of male students is x, and that of female students is 4x / 3
So, x + 4x / 3 = 42
7X/3=42
X=18
Then 4x / 3 = 4 × 18 / 3 = 24
That is, there are 18 boys and 24 girls in the class
