Question

a can made railway track two given station in 16 days and B can do the same job in 12 days of with the help of C they did in 4 days only in how many days C takes to complete the job alone ?​

Answer 1

Answer:

Step-by-step explanation:

A can do it in 16 days,

B can do it in 12 days,

So work done will be lcm of 16,12→ 48

Work done=effecincy* time..

So efficinecy of A=3———(1)

Efficiency of B=4——-(2)

A+B+C takes 4 days…So their total efficiency is 12..

Ie,Efficiency of A+B+C→12——(3)

From 1,2,3

Efficiency of C is 5

Time taken by C to complete 48 work is 48/5=

9 and 3/5 days…
