Given Company A = 20% increase and company B 25% decrease.
ANew=120/100 * Aoriginal
Asked for BNew = what % of Aoriginal. We will look into the two points to evaluate the sufficient condition
1)
The original monthly revenue of Company A was equal to the original monthly revenue of Company B.
Assume AOriginal=BOriginal=100
ANew=120 Bnew=75
Bnew=x*Aoriginal
75=X*100
=> X=75%
2) The increased monthly revenue of Company A was 60 percent greater than the reduced monthly revenue of Company B
ANew=60% Bnew + Bnew
ANew=BNew(160/100)
120 * Aoriginal=BNew(160/100)
BNew=120*100/160*Aoriginal
=3/4*100*Aoriginal
BNew=75*Aoriginal
75% of Aoriginal
Thus C is the option
It is D
Statement 1 says that both companies revenue were same, sa it is X
the new revenue of A will be 1.2X and of B will be .75 X
we want to know reduced revenue of B/actual revenue of A = 0.75x/x
Statement 2 We now have a series of ratios. We can express the increased revenue of A and the reduced revenue of B in terms of the same variable, which means we can also express the original revenue of A in terms of that variable, which allows us to link the reduced revenue of B and the original revenue of A.
