In a survey, it was discovered that 21 individuals read English newspapers, 26 individuals read Hindi newspapers, and 29 individuals read regional language newspapers. Furthermore, 14 individuals read both English and Hindi newspapers, 15 individuals read both Hindi and regional language newspapers, 12 individuals read both English and regional language newspapers, and 8 individuals read all three types of newspapers. How many people read only regional language newspapers?

Solution & Step-by-step Explanation

Let the sets of individuals reading English, Hindi, and Regional newspapers be E, H, and R respectively. We are given: * n (E) = 21 * n (H) = 26 * n (R) = 29 * n (E \cap H) = 14 * n (H \cap R) = 15 * n (E \cap R) = 12 * n (E \cap H \cap R) = 8 The number of people who read only regional newspapers is calculated by subtracting those who read regional along with other languages, while adjusting for the center intersection: Only R = n (R) - n (E \cap R) - n (H \cap R) + n (E \cap H \cap R) Only R = 29 - 12 - 15 + 8 Only R = 29 - 27 + 8 = 10
