=====================================

aim : to find the  least number must be subtracted from 7250 to get the perfect square

=>first , let us find the square root of 7250

=>√7250

=> 85.146........

now let us round of 85.146 to the before hundered

=>85 [approx]

now 85²

=>85* 85

=> 7225

=>so the perfeet square before  7250 is 7225

so the leats number   = 7250 -7225

=>25

∴option [d] is the correct one's
