Solution:
Logic ::
First number on the right hand side is the second number in the left side of equation ( and ) second number on the right side is the sum of two numbers on the left side of the equation.
1 + 3 = 3 (1 + 3) = 34,
5 + 2 = 2 (5 + 2) = 27,
5 + 1 = 1 (5 + 1) = 16,
3 + 5 = 5 (3 + 5) = 58,
then 2 + 4 = 4(2+4) = 46.
Hence, the answer is 2 + 4 = 46.
