Question
A tap of type '5P' can completely
fill a tank in 'P/2' hours, whereas a tap of type '2Q' can fill the same tank in '4Q/5' hours. Quantity I: The sum of 'Q + 10'. Quantity II: The value of '2.75P'. In the question, two Quantity I and Quantity II are given. You have to solve both the Quantities to establish the correct relation between Quantity I and Quantity II.Solution
ATQ,
Let the total work be = 5P Ă— P/2 = 2Q Ă— 4Q/5 (P/Q)2 = (4/5)2 P/Q = 4/5 P = 4a, Q = 5a Q + 10 = 5a + 10 - Quantity I 2.75P = 2.75 Ă— 4a = 11a - Quantity II a = 1 Quantity I = 5 Ă— 1 + 10 = 15, Quantity II = 11 Ă— 1 = 11, Quantity I > Quantity II a = 2, Quantity I = 5 Ă— 2 + 10 = 20, Quantity II = 11 Ă— 2 = 22, Quantity I < Quantity II Hence, Quantity I = Quantity II or No relation
