*CONTENT QUALITY REQUIRED*

6+4=210

9+2=711

8+5=313

5+2=37

7+6=113

9+8=117

10+6=416

15+3=1218


??+??=123

Answer 1

the numbers are 12 and 11

the logic used here is :
for example :6+4=210
add both the numbers and we get 10. we will use 10 at the once and tens place.
now subtract 4 from 6 we will get 2 ,use it at the hundreds place.

apply this logic to any other term of the series given above.....
using this in ?? +??=123
we get two equations x+y=23 and x-y=1
on solving above equations we get the numbers as 12 and 11.

hope this helps you

Answer 2

Hi there!
The Clues referred in the Query follows the same pattern
[ First Digit of RHS is derived by subtracting the no.s n' Last Digits are derived by adding that no.s from LHS ]

♦ 6 + 4 = 210
Here,
6 - 4 = 2 n' 6 + 4 = 10 [ So, RHS = 210 ]

♦ 9 + 2 = 711
Here,
9 - 2 = 7 n' 9 + 2 = 11 [ So, RHS = 711 ]

♦ 8 + 5 = 313
Here,
8 - 5 = 3 n' 8 + 5 = 13 [ So, RHS = 313 ]

♦ 5 + 2 = 37
Here,
5 - 2 = 3 n' 5 + 2 = 7 [ So, RHS = 37 ]

♦ 7 + 6 = 113
Here,
7 - 6 = 1 n' 7 + 6 = 13 [ So, RHS = 113 ]

♦ 9 + 8 = 117
Here,
9 - 8 = 1 n' 9 + 8 = 17 [ So, RHS = 117 ]

♦ 10 + 6 = 416
Here,
10 - 6 = 3 n' 10 + 6 = 16 [ So, RHS = 416 ]

♦ 15 + 3 = 1218
Here,
15 - 3 = 12 n' 15 + 3 = 18 [ So, RHS = 1218 ]

So, ATQ :

?? + ?? = 123
Applying the pattern ( Eqn. ) we've found above, we get :

x-y = 1 n' x+y = 23
Solving..

12 - 11 = 1 n' 12 + 11 = 23
[ Hence, RHS = 123 ]

Therefore,
?? = 12 n' ?? = 11

Hope it helps! :D
