exc4libur · Answer

Terminating decimals are those in which the denominator is a multiple of 2, 5 or both.
(note: an integer is a terminating decimal)

(1) 50 < a < 60   insufic

(2) b = 3   sufic

b=3 and a=9, a/b=3 terminating
b=3 and a=1, a/b=1/3 repeating

Ans (E)

If a and b are positive integers and the ratio a/b is expressed as a decimal, is a/b a terminating decimal?

(1) 50 < a < 60
(2) b = 3

Terminating decimal we get integer is divisible by 5 or 2.
#1 insufficient as b not know
#2 b=3 insufficient as a not know
From 1&2
Sufficient as decimal will be terminating and non terminating
a=52,53,54...

IMO E

(1) 50 < a < 60
(2) b = 3

clearly they are insufficient individually....
combining both we get a=51-59,b=3 then except for 51,54,57(a/b is an int) ....others whose result is a decimal is non-terminating....

OA:C

ostrick5465 · Answer

(1) Not sufficiency
(2) Not sufficiency
Combine (1) and (2) 
if a = 51; b = 3 => 51/3 = 17
if a = 52; b=3 => 52/3 = 17.33333
=> Not sufficiency
 => Choice E
