CExplanation
Let, the numbers are A = x, B = x + 1, C = x + 2, D = x + 3, E = x + 4 sum = x + x + 1 + x + 2 + x + 3 + x + 4 = 5x + 10 Deleting one of the five numbers from the set decreased the sum of the remaining numbers in the set by 20%. new sum = sum - 0.2 sum = 0.8 sum = 0.8 (5x + 10) = 4x + 8 deleted number = 5x + 10 - 4x - 8 = x + 2 = CRelated questions
