Answer:

Sunita completes remaining work in 13.5 days

Step-by-step explanation:

take LCM of 14 and 21 . ie 42

man can do 3 units of work in day

Sunita can do 2 units of work in a day

total work is 42 units

they started working together, and worked for 3 days, number of units of work completed is

3*(3+2)=15 units

remaining work is 42-15 =27 units of work

remaining work is completed by Sunita

in 27/2 =13.5 days

Sunita completes remaining work in 13.5 days
