Aman, Sam and Kiran started working together but after 8 days Kiran left the job and 5 days before the completion of the work Sam also left then, In how many days the whole work gets completed?
ATQ, we can say that Efficiency of, Ram = r, Mohani = m, Aman = a, Sam = s, Kiran = k (r + m) × 24 = (m + a) × 30 = (a + s) × 24 = (r + k) × 36 = (s + e) × 20 = 360 r + m = 15, m + a = 12, a + s = 15, r + k = 10, s + k = 18 (m + a) + (a + d) – (r + m) – (s + k) + (r + k) = 12 + 15 – 15 – 18 + 10 2a = 4 a = 2, m = 10, r = 5, s = 13, k = 5. ATQ, Let work will be completed in w days 2 × w + 13 × (w – 5) + 5 × 8 = 360 2w + 13x – 65 + 40 = 360 15w = 360 + 25 = 385 w = 77/3 days
