1.	In what ratio 57 octane and 63 octane should be mixed to obtain 59 octane?(a) 1:1(b) 2:1(c) 3:1(d) 4:1The question was asked by my college professor while I was bunking the class.This intriguing question originated from Steady-State and Unsteady-State Systems topic in section Introduction to Material Balances of Basic Chemical Engineering
Answer» RIGHT CHOICE is (b) 2:1 Explanation: 591 = 63x + 57*(1 – x), => x= 1/3, => 1 – x = 2/3, => ratio of 57 octane: 63 octane = 2/3:1/3 = 2:1.
