Can an instructor chyme in on this? I cannot understand anyone's answer explanation. I think B is sufficient bc it gives the price and tax rate of both and says that one is greater than the other.

p1,p2 and t1,t2 are unknowns

Statement 1:

Unless you know the exact value of p1 and p2 ,t1 > t2 doesn't conclude anything. INSUFFICIENT

Statement 2:

Unless you know the exact value of p1 and p2 ,p1t1 > p2t2 doesn't conclude anything. INSUFFICIENT

Combining also we can't predict about p1 and p2 individually( Test with Examples)

I read the question the same way! The book says "Is the Total Cost of the computer greater in State A than State B. Therefore I would thought it was referring to P and T... since Total cost seems like that would included tax... but the only way I can rationalize OA being E is if this is misinterpreted. Maybe just poorly worded

We cant find the answer until we dont know the value of P1 & P2

E is the correct answer

S1: Definitely not sufficient

100 = p1, t1 = 10 => price = 110
200 = p2, t2 = 5 => price = 210

S2: A: p1*(1+p1t1/100) B: p2*(1+p2t2/100)
If p1t1 > p2t2 does not imply that the expression will also follow the same rule

Comb:
Does not yield anything

(E) is answer

@ Ganesh

STATEMENT a IS INSUFFICIENT BECAUSE WE DONT HAVE THE EXACT VALUES FOR COST AND TAX

MOVING FORWARD FOR STATEMENT B;

city 1: cost 100, tax 10%
cost*tax= 100x(10/100)=10--------------(i)

city 2:cost 1000, tax 5%
cost*tax=1000x(5/100)=50--------------(ii)

(i) < (ii) as per statement B

so (E) insufficient

E for Answer.

CASE I:

P1=10,t1=1 P2=10,t2=0.5

Here, P1=P2,t1>t2 and (P1)*(t1)>(P2)*(t2) and (total cost in state A) > (total cost in state B)

CASE II:

P1=10,t1=1 P2=20,t2=0.25

Here, P1>P2,t1>t2 and (P1)*(t1)>(P2)*(t2) and (total cost in state A) < (total cost in state B)
