Answer:

According to question,

Ganga begins at 9 am and she does 3 units/hours

Saraswati begins at 10 am and she does 2 units/hours

So by 11 am they complete 5 units

Time =T.W.3+2=245

(4 cycle of 2 hrs each + 4 units left)

And now ganga will complete 3 unit out of 4 units in 1 hr

Now, rest 1 unit work done by = 12

hr

= 912

hr

Hence, Work finished at

= 9 am + 912

hr
