Answer 1

Answer:

hey here is your answer

pls mark it as brainliest

so here we go

let the required four digit number be abcd where digit at thousands place is a hundred place is b tens place is c and that of units ie ones place be d

so the structure of this four digit number=1000a+100b+10c+d

according to the first condition

b=4c (1)

according to the second condition

now we know that third multiple of 3 is 9

so thus

a=9 & a=c+7

ie 9=c+7

so c=2 (2)

according to third condition

now only and only one odd number is possible between 5 and 9 which is nothing but 7

so thus d=7 (3)

substitute value of c in (1)

we get b=8

so our required structure=

1000a+100b+10c+d

=(1000×9)+(100×8)+(10×2)+7

=9000+800+20+7

=9800+27

=9827

thus required four digit number is 9827
