In the correctly worked multiplication problem shown above, A, B, C, D and E are different non-zero digits. What is the valued of D?

(1) A = 3
Let's say
A B * C =  D  E
3 4 * 2 =  6  8
3 8 * 2 =  7  6
3 9 * 2 =  7  8
 Not Sufficient

IMO C

(2) D is an even digit
 Not Sufficient

Both Statements
D is even =  6 
 Sufficient

TestPrepUnlimited · Answer

Statement 1:

Since A is 3, our choices of C are limited to 1, 2, or 3. We may have D = 3, 6, 7, or 9. (38*2 = 76 for example will give D = 7). Insufficient.

Statement 2:

D could be 2, 4, 6, or 8. Insufficient.

Combined:

Combined we can see the only option in both statements is D = 6. Sufficient.

Ans: C

In the correctly worked multiplication problem shown above, A, B, C, D and E are different non-zero digits. What is the valued of D?

(1) A = 3
(2) D is an even digit

(1) A = 3

dont know about b and C
so, D can be any value from 3 to 9
Not sufficient

(2) D is an even digit

dont know about A, B & C
D can be 2, 4,6,8

Not sufficient

(1) + (2) : A = 3 and D is an even digit

C must be 1,2 or 3

1 and 3 cant be possible, so C = 2

D must be 6

Sufficient

Answer C

vatsal323 · Answer

Why can C be just 1 or 2? Why can't it be 4, 5, ..., 9?

akshay0511 · Answer

vatsal323 
 When we combine the two statements, the only possible values for C are 1,2 and 3 as 4 onwards the value of D becomes a two digit number (4 x 3= 12) and so on, Hence the only values of C are 1,2 and 3 in which D has to be an even digit therefore C is 2 which gives D as 6.

aliraza506 · Answer

When A is 3, C equal to or greater than 4 would make the result a 3-digit number, the question has set the constraint that the result should be a two digit number.
For example, 30*4=120
