Answer:

Unknown

Step-by-step explanation:

The four-digit number can be written as abcd and can be expanded as 1000(a)+100(b)+10(c)+1(d).

According to the question,

a=b/4, c=a+b, d=2c

Therefore,

a=b/4, b=b, c=5b/4, d=5b/2

Four digit number is 250b+100b+25b/2+5b/2

Which is equal to 350b+15b= 365b= 365*Second digit.

Using trial and error:(We know that the number is a four digit)

365*1=365

365*2=730

365*3=1095

365*4=1460

365*5=1825

365*6=2190

365*7=2555

365*8=2920

365*9=3285

365*10=3650

365*11=4015

365*12=4280

365*13=4745

365*14=5110

365*15=5475

365*16=5840

365*17=6205

365*18=6570

365*19=6935

365*20=7300

365*21=7665

365*22=8030

365*23=8395

365*24=8760

365*25=9125

Sorry, I must have made a mistake. This is wrong :(
