Answer 1

Correct answer is (c) ratio of initial weight of aircraft to that of final weight of aircraft

The explanation: The fuel ratio is the ratio of initial weight of aircraft to that of final weight of aircraft. It is denoted by ω. The equation is given by ω=\(\frac{W_i}{W_f}\) where Wi is initial weight of aircraft and Wf is final weight of aircraft.
