if 4 tank fill in 2hour 20 minutes =140min
-so time to fill 1 tank =140/4=35min
now time to fill 7tank =7*35=245min=4hour 5min.

to fill 7 tanks time taken =?
convert 2 hrs into min
2×60=120min
time taken to 4 tanks=120+20=140min
time for filling 7 tanks=
4___140
7___? (cross multiplication)
=7×140/4
=7×35
