SSC MTS 2 Aug 2019 Shift 2 Paper

⇒ 2(A + B + C) = 47 (Efficiency)
⇒ A + B + C = 23.5 ---- (1)
⇒ B + C = 12 ---- (2)
From (1) and (2)
⇒ A = 11.5
⇒ A alone can do the same work = total work/efficiency of A
⇒ A alone can do the same work = 300/11.5 = 600/23 days
∴ A alone can do the same work in 600/23 days.
