Quantitative Aptitude - Algebra - Maxima Minima - If a, b, c, and d are integers Quantitative Aptitude - Algebra - Maxima Minima Question If a, b, c, and d are integers such that a + b + c + d = 30, then the minimum possible value of (a - b)^2 + (a - c)^2 + (a - d)^2 is Answer 2 Solution From CAT 2017 - Quantitative Aptitude - Algebra - Maxima Minima, we can see that, a + b + c + d = 30 a, b, c, d are integers. (a – b)^2 + (a – c)^2 + (a – d)^2 would have its minimum value when each bracket has the least possible value. Let
