Answer:

4998

Step-by-step explanation:

The four digit number the last digit is twice the first digit the second and the third are the same the number formed by the last two digit is twice the number formed by thr first two digit​

Let say Number = ABCD

D = 2A

B = C

10C + D = 2(10A + B)

=> 10B + 2A = 20A + 2B

=> 8B = 18A

=> 4B = 9A

A = 4   & B = 9  C = 9  D = 8

ABCD = 4998
