Ratios - Focus on Key Takeaways from this Question

by ankur.agrawal » Sat Apr 16, 2011 10:12 pm
In 1994, Company X recorded profits that were 10% greater than in 1993, and in 1993 the company's profits were 20% greater than they were in 1992. What were the company's profits in 1992?

(1) In 1994, the company's profits were $100,000 greater than in 1993.

(2) For every $3.00 in profits earned in 1992, Company X earned $3.96 in 1994.

x is profit in 1992, 1.2x is profit in 1993,
10% on 1.2x is 1.32x is profit in 1994

1) 0.32x = 100K+0.2x
2) 3$ is profit in 1992 and ~4$ in 1994

Is it A...
First take: 640 (50M, 27V) - RC needs 300% improvement
Second take: coming soon..

agree with above poster, to me answer is also A
it is clear that 1 st is sufficient.to the st 2
(2) it simply restates the terms of problem in other language
For every $3.00 in profits earned in 1992, Company X earned $3.96 in 1994.
it means that every 1$ earned in 1992 resulted in (3.96/3)-1.32$ earned in 1994
and if x$ earned in 1992, then in 1994 it will be 1,32x

our problem states
x-in1992
1,2x-1994
1,2*1,1x=1.32x as we see it is the same as above
so insuff
