The correct Answer is:
To solve the problem step by step, we need to determine the minimum possible number of students from the Engineering background in a class of MBA students. We will start by analyzing the percentages given for each background. ### Step 1: Understand the Percentages The percentages of students from different backgrounds are: - Science: 16.66% - Commerce: 12.5% - Arts: 66.66% - Engineering: Remaining percentage ### Step 2: Convert Percentages to Fractions To make calculations easier, we can convert the percentages into fractions: - 16.66% = 1/6 (approximately) - 12.5% = 1/8 - 66.66% = 2/3 (approximately) ### Step 3: Find the Least Common Multiple (LCM) To find the total number of students, we need to find the least common multiple (LCM) of the denominators of the fractions: - The denominators are 6, 8, and 3. - The LCM of 6, 8, and 3 is 24. ### Step 4: Calculate the Number of Students from Each Background Now, we can calculate the number of students from each background based on the total number of students being 24: - Science: (1/6) of 24 = 4 students - Commerce: (1/8) of 24 = 3 students - Arts: (2/3) of 24 = 16 students ### Step 5: Calculate Total Students from Known Backgrounds Now, we add the number of students from Science, Commerce, and Arts: - Total from known backgrounds = 4 (Science) + 3 (Commerce) + 16 (Arts) = 23 students ### Step 6: Determine Students from Engineering Background To find the students from the Engineering background, we subtract the total known students from the total class size: - Total students in the class = 24 - Students from Engineering = 24 - 23 = 1 student ### Conclusion The minimum possible number of students from the Engineering background is **1 student**. ---
