Question

$5+3+2=151022$
$9+2+4=183652$
$8+6+3=482466$
$5+4+5=202541$
Then . . .
$7+2+5=?????$

Answer 1

Condition (1)

First two digit

$5\times 3=15$

$9\times 2=18$

$8\times 6=48$

$5\times 4=20$

Condition (2)

First and last digit

$5\times 2=10$

$9\times 4=36$

$8\times 3=24$

$5\times 5=25$

Condition (3)

$(IInddigit+IIIrddigit)\times \left(Istdigit\right)-\left(IInddigit\right)=solution$

$(3+2)\times 5-3=22$

$(2+4)\times 9-2=52$

$(6+3)\times 8-6=66$

$(4+5)\times 5-4=41$

Then, condition (1) (2) and (3) to,

$5+3+2=151022$

$9+2+4=183652$

$8+6+3=482466$

$5+4+5=202541$

Then,

$7+2+5=143547$

Hence, this is the answer.
