Thanks Hi Roland2rule, Let's take a look at your question. If C denotes cats and D denotes dogs, then, $$\frac{C}{D}=\frac{5}{6}$$ $$6C=5D...(i)$$ If there are 18 fewer cats then dogs, we can write it as, $$C=D-18$$ Substitute C in eq(i), $$6\left(D-18\right)=5D$$ $$6D-108=5D$$ $$6D-5D=108$$ $$D=108$$ Therefore, Option D is correct. Hope it helps. I am available if you'd like any follow up. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee.
