Answer» Answer: 25 days Step-by-step explanation: a=b+C, a+b=10, c=50, b=? work done by a and b in 1 day=1/10 work done by c alone in 1 day=1/50 total work done by a,b,c in 1 day=(1/10)+(1/50)=(6/50)=(3/25) work done by a in 1 day = work done by b and c in 1 day = x therefore, x+x=(3/25) 2X=(3/25) x=(3/50) work done by b and c in 1 day = (3/50) work done by b alone in 1 day =(3/50)-(1/50)=(2/50)=(1/25) B alone can work in 25 days. |
