Question
In a village with a population of 8,500 people, 80% of
them are adults. Among these adults, only 75% possess a ration card. Furthermore, 60% of the ration card holders can speak Hindi. Determine the total number of people in the village who can speak Hindi.Solution
Number of adults in the village = 8500 X 0.8 = 6800Number of people with a ration card = 6800 X 0.75 = 5100Number of people who speak Hindi = 5100 X 0.6 = 3060
