If n > 0, which is greater, 20 percent of n or 10 percent of the sum of n and 05 ?
(1)) n < 01
(2)) n > 001
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
D ) EACH statement ALONE is sufficient
10 percent of the sum of n and 5 is always greater….
i agree with V Pat. Each alone is sufficient. D
a is ans
if we take any numer lessthan 1 20% of it is always less than 10% of 5+less than 1
if we take more than 1
20% of 2=.4
10% of 2+5= .7
if we take n=40
20% of 40=8
10% of 40+5=4.5
0.4less than .7
8 is greater than 4.5
Is 01 supposed to mean .01 (decimal point missing?). In which case, A could be the answer …
A
for the second case 0.1n + 0.5 > 0.2n only for n
both alone
a
Agree with Nrip and 303.
a

A it is.
The undoubt ans…:)
we are trying to compare – .2n and .1(n + 5)
==> 0.2n ?? (0.1n + 0.5)
Substracting 0.1n from both sides.
==> 0.1n ?? 0.5
Multiplying by 10 on both sides..
==> n ?? 5…
so it boils down to whether n is lessthan, equal or greater than 5.
Option 1, n 1, can be 4 or 6, so doesn’t answer the Q.
D
Ans: D.
can any1 explain why B cant answer the question?
Take the Gmat, Please provide the answer.
my ans is A…. in second statement n can be more than 10
Unable to understand. Can some one exlain in detail
A
Arun here is the explaination on why i can not be B
n>.001 What if n = 200
20% n = 40
10% + .05 = 20.05
now what if n = .01
20% n = .002
10% + .05 = .001 + .05 = .051
So the B is not conclusive. Hence A only..
hey i think its D…………..how can it be A can anyone explain me…..
