(2)
n=20q +3
if n=13, then q=0,5

is it possible for q to be 0,5?

I never encountered such values for quotent in remainder questions...

n/25=a+13 ---given

A)so n=a*25+13 which says 25a is multilple of 25

n=38,63,88 Insuff

B)n>20 but the end limit is not given ! Insuff

Togethere we know n>20 and n <100

still the numbers 38,63,88 holds good

OA E

Vishu
KILL !! DIE !! or BEAT my FEAR !!! de@D END!!

First of all, it is 25 not 20

N= 25q+13

q=0,1,2,3, ..etc

Remember 12 divided by 38 , and the remainder is 12

or if X<Y and X is divided by Y

The remainder is X itself. Put that in a flash card, I DID! ;-)

I think the OA is C)

n=63

13/20 does not give a remainder of 3.

One more vote for C.

n = 25a+13

1: n<100

n could be 38, 63, 88.

2: n = 20b+3

Insuff

Combining you'll get

n = 63, as 38 and 88 when divided by 20 do not leave a remainder of 3
