Answer» Answer: A+B = 16 days Efficiency of A+B = 3 Efficiency of B+C = 2 A’s efficiency = 3-B C’s efficiency = 2-B A’s efficiency =3-B which is equal to 3 (2-B) 3- B = 6 - 3B 2B = 3 Hence B=1.5 and hence C’ s efficiency =0.5 and A’s efficiency = 1.5 Total A+B+C Efficiency = 3.5 Total work =48 ÷ 7/2 =96/7 =13-5/7 days |
