$\text{ As} \ 72496 \ \text{is to} \ 1315 \implies 13=7+2+4, 15=9+6$ $\text{And} \ 62134 \ \text{ is to } \ 97 \implies 9=6+2+1, 7=3+4$ $\text{And} \ 85316 \ \text{ is to } \ 167 \implies 16=8+5+3, 7=1+6$ $\text{Therefore} \ 28439 \ \text{ is to } \ \boxed{1412} \text{Because} 2+8+4=14, 3+9=12$

Hence the correct answer is $\boxed{1412}$

First add the first 3 digits and then write it. after that add the last two digits and also write that number next to the sum of the first 3 digits

Simply asuume that the number is "abcde"=FS. Where F=(a+b+c), and S=(d+e). Then 28439 is F=(2+8+4)=14, and S=(3+9)=12.So FS=1412

So Easy...

add 1st three and last two digits and join both answers...

Sum of the first three digits next to the sum of the last two digits

(2+8+4)(3+9)

easy ... just, sum : digit 4 and digit 5 => $3 + 9$ = $12$ then, sum : digit 1, digit 2 and digit 3 => $2 + 8 + 4$ = $14$ so, 28439 is to $1412$

Take right side two digit addition first and write it first then add all left digit and write it leftside of written ans

The sum of First three digits of no.s represent starting digits of the result no. and last two digits represent following digits of resulting no.

Hence 2+8+4=14

3+9=12 Hence answer is 1412
