Explanatory Answer
Method of solving this CAT Quantitative Ability Question from Algebra question
(b) Basically, the question is of weights, so let us analyse them.
4 Rubies weight as much as 3 Emeralds
Cost of 4 Rubies = 16 crores
Cost of 3 Emeralds = 15 crores
All Rubies, multiple of 4 allowed, is the best deal,
so 12/0.3 = 40 Rubies ≡160crores
