Let take capacity of tank=900 L
First outlet van fill the 900 L in 9 hours.
=> In 1 hour it can fill 100 litres.
For second outlet, It can fill 180 L in 1 hour(900/5=180)
Now both the outlets are open,
For 1st hour= 100L+180L=280 L
For second hour=280+280=560
For 3rd hour=560+280=840L
Now 60 Litres have to fill.(900-840=60)
Both outlets can fill 180 L in 1 hour.
Time required them to fill 60L =20 mins.
So, Total time required fill the whole tank=3.20 Hours.
