a. 75-n > n-50

125 > 2n

62.5 > n

--------n-------50-------------n---62.5--------------75

SUF

b. n > 60

N can be in three different zones and the relative distance of N to 50 and 75 can change,


50----------60--n--62.5-----n------------75-----------------n--------

Is the value of n closer to 50 than to 75?

a. 75-n > n-50
b. n > 60

75+ 50 /2 > n

n < 62.5

Insuff..


2 )
n > 60

insuff

together

60 < n < 62.5

62.5 is the midpoint between 50 and 75... but n < 62.5
so n is nearer to 50

Hence IMO D

Light Weight Baby :-) Ronnie,


I think its A) and not D).Also when you use stmts together like u did should be C) and not D). May be its a typo also.

Stmt I

75-n > n-50

75+50>2n

125>2n

2n < 125

n<62.5

Definitely closer to 50 than 75 since 62.5 is the midpoint between 50 and 75

SUFF

Stmt II

n > 60

If its 61 then its closer to 50
If its 69 then its closer to 75

INSUFF

Choose A)
