Given : quantities that vary directly and indirectly
To Find : List the pair
Solution:
directly
=> x ∝ y
=> x/ y = constant
Distance ∝ Speed
Distance ∝ Time
Current ∝ Voltage
Temperature ∝ Heat
Work Done ∝ Time
Work Done ∝ Man power
Cost ∝ Fuel Consumption
Indirectly x ∝ 1/y
=> xy = constant
Current ∝ 1 / Resistance
Speed ∝ 1/ Time
Mileage ∝ 1/ Fuel Consumption
Time ∝ 1/Man power
Cost ∝ 1/Mileage
