Q: Coefficient of apparent expansions of a liquid in two different vessels are a and b. then the real coefficient of expansions of liquid, if the ratio of volume expansion of vessels is x : y

(a) $ \displaystyle \frac{bx-ay}{x-y} $

(b) $ \displaystyle \frac{ay + bx}{x+y} $

(c) $ \displaystyle \frac{ay-bx}{x-y} $

(d) $ \displaystyle \frac{ay+bx}{x-y} $

Ans: (a)
