Dear  student,

n/810 =0..............................................1

1000×n/810 = d25...........................2

Subtract eqn  1 from eqn  2

999n/810 = d25

n=d25×810/910

n=d25×30/37

As n is an integer, so d25 must be completely divisible by 37.

As d is a single digit number, the only multiple of 37 that makes it possible is 25 (37×25 = 925).

Hence d=9.

Hence n = 925×30/37

n=750
