Question
Pipe A alone fill the tank in x hours and Pipe B alone
fill the tank in (x – 4) hours. If the efficiency of pipe B is double of pipe A and pipe A fill the tank is 45 liters per hour, then what is the capacity of the tank?Solution
Pipe A alone fill 45 liters per hour, so Pipe B alone fill 90 liters per hour. Capacity of the tank = T => T/45 – T/90 = x – (x – 4) => 2T – T = 360 => T = 360 liters
Running time T(n) where 'n' is the input size of the recursive algorithm given as : T(n) = c + T(n-1), if n > 1 ; T(n) = d if n < 1. The order of the a...
