If each of c, d, and e is a one-digit number, what is the value of e? (1) c = 1 and c*d*e = 24 (2) d/c = 4 and d/e = 2/3 (1) d and e can take following values: (-4 , -6) , (4,6), (-6, -4), (6,4 ) Insufficient (2) d/c = 4: d and c have same sign d/e = 2/3: d and e have same sign ==> c,d and e have same sign Also, d= 4c = 2e/3 e= 6c insufficient (1) & (2) c=1 which means c, d and e are all positive (from statement 2) and e= 6 Sufficient --C-- correct me if I missed something

(1) c = 1 and c*d*e = 24
(2) d/c = 4 and d/e = 2/3
(1) d and e can take following values:
(-4 , -6) , (4,6), (-6, -4), (6,4 )
Insufficient
(2) d/c = 4: d and c have same sign
d/e = 2/3: d and e have same sign
==> c,d and e have same sign
Also, d= 4c = 2e/3
e= 6c
insufficient
(1) & (2)
c=1 which means c, d and e are all positive (from statement 2)
and e= 6
Sufficient
--C--
correct me if I missed something Edited: If each of c, d, and e is a positive one-digit number, what is the value of e?

(1) c = 1 and c*d*e = 24
(2) d/c = 4 and d/e = 2/3 (1) 1*d*e = 24 OR d*e = 24. We could have d/e as 4/6 (e could be 4 or 6) but we could also have d/e as 3/8 (e could be 3 or 8). Thus e can take 4 values. Not sufficient. (2) d=4c, and 3d=2e or e=3d/2 OR e=3*4c/2 = 6c So we have e = 6c, where both c and e have to be positive one-digit numbers. The only case possible is c=1, e=6 (because for c=2 or 3 etc, e will be two digit number). So Sufficient. Hence B answer

No. Single-digit numbers are: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

B.
under the condition that d,c, and e are single digit.
d/c can be 4/1 or 8/2,
d/e= 2/3 or 4/6
Answer can be concluded from both
