Having $5$ at units place, find the square of the number $185$ .
$48034$
$15620$
$34225$
$83450$

$185$ $=$ $(200 - 15)$
$185^{2}$ $=$ $(200 - 15)^{2}$
$(200 - 15)^{2}$ $=$ $200^{2}$ $+$ $15^{2}$ $-$ $2 \times 200 \times 15$
$185^{2}$ $=$ $40000$ $+$ $225$ $-$ $6000$
$185^{2}$ $=$ $34225$
Hence, Option A is correct.
