What is the value of y?

(1) When y is multiplied by 6, the result is between 40 and 45.

this gives us value of y from 6.33<y<7.66 ...insuff
(2) When y is multiplied by 3, the result is between 19 and 23.
6.66<y<7.5..... insuff
(1) + (2) give 6.66<y<7.5 ....still insuff

it is NOT said that y is integer ..so let's assume y= 6.5, 6.6 or 7

all of these satisfy (1) and (2)
so (E)
GMATPowerPrep Test1= 740
GMATPowerPrep Test2= 760
Kaplan Diagnostic Test= 700
Kaplan Test1=600
Kalplan Test2=670
Kalplan Test3=570
