If n > 0, which is greater, 20 percent of n or 10 percent of the sum of n and 0.5 ?
(1) n < 0.1
(2) n > 0.01
answer A
(1) n < 0.1
(2) n > 0.01
answer A
let's beat GMAT.
(1) n < 0.1
Here if you take any value for n i.e less than 0.1 and greater than zero.
20% of n will always be very small as compared to 0.5
for example, say n = 0.02
Now 20% of 0.01 = 0.004
20% of any number number which is less than 0.1 will always give smaller number than 0.5

(2) n > 0.01
Consider the above ex which says
20 percent of n < 10 percent of the sum of n and 0.5
and take n = 10, then
20 percent of n > 10 percent of the sum of n and 0.5
(2 > 1.5)
