Study the following table carefully and answer the given question. Number of Candidates Appearing For Interview for a post of Assistant Engineer in Various PSU’s PSU Appeared Candidates % of Qualifying Candidates ECIL 150 20% NPCIL 300 17% CIL 125 40% NHPC 150 36% EIL 140 56% The Ratio of number of Candidates who did not qualify in NHPC and number of Candidates who did not Qualify in NPCIL respectively is: Correct Answer 32 : 83
Calculation:
The number of candidates who appeared in an Interview for NHPC = 150
% of qualifying candidates for NHPC = 36%
The number of candidates qualifies for the Interview in NHPC = (36/100) × 150
⇒ 54
The number of candidates who did not qualify for the Interview in NHPC = 150 - 54
⇒ 96
The number of candidates who appeared in an Interview for NPCIL = 300
% of qualifying candidates for NPCIL = 17%
The number of candidates qualifies for the Interview in NPCIL = (17/100) × 300
⇒ 51
The number of candidates who did not qualify for the Interview in NPCIL = 300 - 51
⇒ 249
Now,
The Ratio of number of Candidates who did not qualify in NHPC and number of Candidates who did not Qualify in NPCIL = 96 : 249 = 32 : 83
Therefore, the correct answer is 32 : 83.
