Question

in a combined testin math and chemistry84% candidates passedin maths and 76% in chemistry and8%failed in both the percentage of failed candidates

Answer 1

% student failed in maths = 100 - 84 = 16%

% students failed in chemistry = 100 - 76 = 24%

Failed in both = 8%

Total % students failed = 8 + (16 - 8) + (24 - 8) = 8 + 8 + 16 = 32%

Total % students passed = 100 - 32 = 68%
