CrackVerbalGMATsince given that y is an integer so we need to test all given options of y where we always get an integer value ( for given options) which is at y= 14 only..
though other possibilities of y are as follows which when divided by 11 gives remainder 3
y =3,14,25,36,47,58
and y+1 ; 4,15,26,37,48,59
A. 2Y + 2 ; ( check at y ,14,) yes possible
B. 1.5Y + 9. ; ( check at y = 14 (possible)
C. 2.5Y – 5.; ( y = 14, possible)
D. 3Y + 3. ; ( y =14, possible)
E. 3Y – 5 ; ( y = 3 possible but not at y = 14,)
we see that only option E is not valid for integer values >11 at y = 14 ;

When the integer Y is divided by 11, the remainder is 3. Which of the following can't be a multiple of (Y+1)?
A. 2Y + 2.
B. 1.5Y + 9.
C. 2.5Y – 5.
D. 3Y + 3.
E. 3Y – 5.
let y =14
option E ; is prime no
IMO E
If Y = 3, then the remainder for \(\frac{3}{11}\) is 3 which satisfies the constraint mentioned.
In that case Option E = (3*3) - 5 = 4, which is a multiple of Y + 1
Here B or C could be the answers, as they are not multiples of 4 when Y = 3.
Just want to know if I am on the right track here. Thanks.
