Hi..

statements..


(1) The product of the three integers is 90.
\(90=2*3*3*5\)
various combinations of 3 integers can be made 2*5*9 OR 3*5*6..
insuff

(2) One of the integers is twice one of the other two integers.
various combination..
2, 4,8
7,8,16
insuff

combined..
90=2*3*3*5...
if one number is twice is DOUBLE of the other , possible case is x and 2x.. only 2 and 2*3 possible ..
so integers are 3, 5,6..

ans 3
suff

C

(1) The product of the three integers is 90.

(2) One of the integers is twice one of the other two integers.



The answer is C?

various combinations can be formed from 1,
2,9,5
3,5,6
2,3,15

using 2, we see that only (3,5,6) qualifies.
hence 1+2 = C

You forgot 1 more combination to statement 2 - 1,2,45 would also work.

Thus - Answer E

Greater than 1. You are considering 1. The answer is C.
