​

Answer 1

Answer:

Step-by-step explanation:

The explanation of your question is :

Total Students Taken = 60 Student's

Judo : Karate = 8 : 4

=>  2 : 1

Judo : Both : None = 14 : 7 : 7

=> 2 : 1 : 1  => 2X, X, X                  

=> 2x + x + x = 4x = 60

=> x = 15  

So,

• 30 students learn only Judo.

• None learn only Karate.

• 15 students learn both.
