If 635 183033 483 321265 394 271236 Then 565Solution635 18

If

6+3+5 = 183033

4+8+3= 321265

3+9+4= 271236

Then

5+6+5=??

Solution

6+3+5 = 18 30 33
4+8+3= 32 12 65
3+9+4= 27 12 36
p+q+r= A    B   C
A=p x q
B=p x r
C= p x q + q x r (then the answer is reversed ( 5x6 + 6x5 = 60, reversed is 06))

Ans: 302506
