Question

the sum of the numbers of boys and girls is 150 . if the number of boys = x then the number of girls becomes x% of the total number of student . find the total numbers of boys in the school​

Answer 1

Answer:

60

Step-by-step explanation:

Let number of boys =x 

⟹ number of girls D=150−x 

given that , (150−x) is x% of total(150)

⟹150−x=100x×150

150−x=23x

25x=150⟹x=60

∴ numbers of boys is 60

Answer 2

Answer:

boys = 130

girls = 20

Step-by-step explanation:

x + x/150 * 100= 150

x + (2x/3) = 150

3x + 2x = 450

5x = 450

x = 130

boys = 130

girls = 20
