Question

Solve if you are Genius
4 + 2 = 4
5 + 3= 10
6 + 4= 18
Than
8 + 6= ??

Answer 1

First number + second number
replace this by
first number * (second number - 1)

4 + 2 = 4 * (2 - 1) = 4
5 + 3 = 5 * (3 - 1) = 10
6 + 4 = 6 * (4 - 1) = 18
so
8 + 6 = 8 * (6 - 1) = 40


Ans is 40

Answer 2

Answer is 40
4*(2-1)=4
5*(3-1)=10
6*(4-1)=18
then
8*(6-1)=40
