Best answer 4 votes 4 votes Let the fraction of quantity replaced be $x$ and initial quantity be $y$. $0.6 y - 0.6 xy + 0.22 xy = 0.42y$ $\\\implies 0.6 - 0.38x = 0.42\\\implies x = \frac{18}{38}= \frac{9}{19}$ Arjun answered Dec 29, 2016 selected Aug 14, 2019 by Bikram Arjun comment Share Follow See all 0 reply Please log in or register to add a comment.
