Question

7/2 times the square root of students in a class are selected for a club and remaining two are selected for other club then calculate the total number of students in the class​

Answer 1

Answer:

The total number of students is 16.

Step-by-step explanation:

Let the total number of students be x.

Then Number of students playing in other club =7/2$\sqrt{x}$

Therefore,

x=7/2$\sqrt{x}$+2

x−7/2$\sqrt{x}$−2=0

y² − 7/2 y−2=0, where y² =x

2y²−7y−4=0

2y² −8y+y−4=0

2y(y−4)+(y−4)=0

(y−4)(2y+1)=0

y=4

x=y²=16

Hope this answer helps you out.
