Answer 1

Step-by-step explanation:

let's work is W

ramu can do work in 16days

raju's 1day work=W/16

ramu can do in 64/5 days

ram's 1day work=W×5/64

geeta can do in 32 days

geeta's 1day work=W/32

total work W

raju's 4 days work=W/4

now suppose the days of work was n

3W/4=n×W/32+(n-3)×W×5/64

n=63/7=9day

thus the work would be complete in 9 days
