ATQ, Time taken by ‘Amit’ to complete the work = 20 days Therefore, time taken by ‘Chirag’ to complete the work = 20/0.8 = 25 days Time taken by ‘Bhuvan’ to complete the work = 25 + 5 = 30 days Let the total work = 300 units Efficiency of ‘Amit’ = 300/20 = 15 units/day Efficiency of ‘Bhuvan’ = 300/30 = 10 units/day Efficiency of ‘Chirag’ = 300/25 = 12 units/day Work done in 3 days = (15 + 15 + 10 + 15 + 12) = 67 units Work done in 12 days = 67 × 4 = 268 units Therefore, efficiency of ‘Dinesh’ = (300 – 268)/8 = 4 units/day Therefore, d = 4 Statement I: 7.5d + 120 = 30 + 120 = 150 Therefore, statement I is true Statement II: Efficiency of ‘Amit’ = 15 units/day Efficiency of ‘Dinesh’ = 4 units/day Required % = {(15 – 4)/4} × 100 = 275% Therefore, statement II is true. Statement III: Time taken by ‘Bhuvan’ to complete the work alone = 30 days 3d + 28 = 12 + 28 = 40 days Therefore, statement III is incorrect
