Step-by-step explanation:
2.
six tanks can be filled in 4 1/2 hours= 9/2 hours
1 tank can be filled = 9/(6x2) = 3/4 hours
4 tanks can be filled = 4 X 3/4 = 3 hours
In 12 hours 4 X 4 = 16 tanks will be filled.
3.
in a scout camp food provision for 300 students 42 days
no of students increase no of days will decrease
so, this is inverse variation
50 more students joined
total no of students= 300+50=350
no of days provision will lost= 300 X 42/350
=36days
