to me it is more of SC + CR( the Vs.a)

from 1

only one candy bar reduction is mentioned and nothing is said in the stem that reduction is the same for all candy bars OR EVEN OF ALL THE BARS ARE THE SAME.(we dont know if this one is represetative for the whole patch)

from 2
we can never know the percent reduction untill we know the original price

both

still insuff

:wink: I am not sure if we need to bring up SC here too. BTW you are right wrt to the wordings in which case answer should be E.

However, if we consider that the price of ALL candy bars is reduced by 36 cents ( not just one bar ) then answer should be C.

i thought we can probably assume here that the price of all candidates reduced by same amt..
question is not testing that.
But probably -

% price reduction = \frac{(new price - old price) *100}{old price}

A - let the original price be $1, then % price reduction = (-36)/100 = -36%
but if the original price is $2, then % price reduction = (200-36-200)/200 = -18%

so insufficient.

B - 144 candidate bars - saving %51.84
so 1 candidate bar saving = 51.84/144 = $0.36.. which is same as 1... so insufficient.

together both the statements are not going to bring any thing different.

so E.

shouldnt the ans be 'C' ?

let the original price of candy bar be x

hence, from stmnt 1 & 2, we get

144(x) - 144(x-0.36) = 51.84

from this, we would get the original price of the candy bar and the reduced price would be x - 0.36.
we can know the difference in percentage...

people ansering E, pls explain..

To some degree I agree with answer c, statement 1 is insufficient, statement 2 alone insufficient but statement 2 tells us that he saves 36 cents per candy bar when buying wholesale. Both combined he reduces by 100 % since 36/36.

Statement 1 and 2 basically say the same thing.
Stmt 1 says - the price of ONE candy bar is reduced by 36 cents .
Stmt 2 in disguise , also says the same ( gives the same info that price of one candy is reduced by 36 cents).

But To calculate the percent reduction in the price of the any commodity , you need the original price of the commodity. If original price of a candy , or new reduced price were given then either of the statements would have sufficed.

Let X be the original price and Y be the reduced price .
Hence % reduction P = (X-Y)/X * 100 .
We only know X-Y=0.36 , from Stmt1/Stmt2 , need need value of X or Y to calculate.

Hope that helps
