since there's only 5 digits at the answer, and A is the second number from E x 4, so A must be 2.

since E x 4 = _ 2 and E is more or equal 8, so E must be 8.

since B x 4 is less than 10, than B must be 1

since D x 4 + 3 = _1, yhan D must be 7

since C x 4 must be more than 30, C must be 6 or 9 (7&8 already been used). and with a little trial C = 9.

A = 2
B = 1
C = 9
D = 7
E = 8.
Prove = 21978 x 4 = 87912

so the answer is c) 8

c)8

E represents 8.

A B C D E *4 = E D C B A
2 1 9 7 8 *4 = 8 7 9 1 2

So, E = 8
