◆Hey There◆
INFO
1) ONE hour work of all three is 1/6
2) after two hours, C is closed
INFERENCE
1) In 2 hours all three would do 2/6 of work =1/3 of work..
2) remaining 2/3 rd of work is done by all three in 4 hours and by ONLY a and B in 7 hrs..
SOLUTION..
therefore lets find how much time C will take to complete this--
one hour work- 1/4-1/7=3/28..
so C takes 28/3 hour to complete 2/3 work..
so C will complete the entire work in 28/3 * 3/2=14 days..
C.
Hope You Like It.
