Question

6+2+4=24,9+1+3=73,4+8+7=31 then 5+9+6=???

Answer 1

Answer:

Step-by-step explanation:

6+2+4=12+12=24, 9+1+3=13+60=73, 4+8+7=19+12=31, 5+9+6=20+60=80.

Answer 2

Answer:

70

Step-by-step explanation:

6+2+4=24,

=6^2 + 2^2 -4^2

=36 + 4 -16

= 24

9+1+3=73,

= 9^2 + 1^2 -3^2

=81+1-9

= 73

4+8+7=31

=4^2+8^2 -7^2

=16+64-49

= 31

5+9+6=

= 5^2 +9^2 -6^2

= 25 +81 -36

= 70

logic is that if

a+b+c = d then

a^2 + b^2 -c^2 = d
