Step-by-step explanation:
From the diagram attached,
Percentage of total students that like watching television = [(WnR)/μ]×100......... Equation 1
The number of students that like watching television and reading (WnR) = 70
The total number of students (μ) = 40+20+70+10
The total number of students (μ) = 140
Substitute these values into equation 1

Percentage of total students that like watching television = 1/2(100)
Percentage of total students that like watching television = 50 %
