Venn diagram
CALCULATION:
Let athletes who love only walking, only running, and only jogging is ‘x + 20’, ‘x’, and ‘2x’ respectively.
Athletes who love all the three = 20
Athletes who love only walking = 20 × (100/40) = 50 = x + 20
⇒ x = 30
Athletes who love only walking and running = 25% of 2x = 25% of 60 = 15
