If the price of a magazine is to be doubled, by what percent will the number of magazines sold decrease?
(1) The current price of the magazine is $1.00.
(2) For every $0.25 of increase in price, the number of magazines sold will decrease by 10 percent of the number sold at the current price.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

Why NOT B
Lets say for x Rs : y Books are sold
Then 1.25x Rs : .9y books wil be sold
In this we didn’t used Statement 1
Hi Chinu,
but with B alone we cant find out % decrease of magazine sale when the price is doubled.
I think it should be C.
I tink the ans is C

The answer is B.
Since in the question percentage is been asked not actual number of magazines decrease .
Suppose X price y copies got sold
now 2x price 4y/5 nmber of copies
suppose y is 100 and then 4y/5 is 80 ie 20 % decrease right .
there fore (100-80 )/100=20% decrease .
this doe not use A and does not even need it .
Yes the answer is B.
Statement 2 says that if the price increases by 25% the number of magazines sold will decrease by 10%.
Therefore if the price increases by 100% (i.e price is doubled) the no of magazines sold will decrease by 40%.
Therefore statement 2 alone is sufficient!
Sorry the answer is C and not B.
the price increase is not represented in %. Hence we need statement 1 as well.
can any body restate on ground zero basis
my ans is c

A,D are out, since (1) gives you no idea how the price relates to quantity demanded.
(2) is also insufficient by itself. To see this, look at the given case where the product is a dollar. then doubling we lose 40% quantity sold, since that is a 25 cent increase 4 times, where each time represents a 10 % loss in the original price. Now take it a step further. Assume the original price is now two dollars. If the price doubles, it is 4 dollars and then we lose 80% sold based on condition (2), i.e. the price goes up 8 quarters’ (.25) worth and each .25 increase still creates 10 % loss each time. So since 40 % does not equal 80 %, statement (2) is not sufficient and must be accompanied by statement (1) Thus the answer is C
