Explanation to Puzzle Answer

| Comment 6 of 7 |

(In reply to Puzzle Answer by K Sengupta)

R(x, y) = x(x+y) + min (x, y)

A table is furnished hereunder supporting the veracity of the abovementioned functional relationship:

x: 1 3 4 5 6 8 9

y: 1 8 7 2 0 3 4

R(x,y): 3 36 48 37 36 91 121

Accordingly, do satisfy the bivariate functional relation in terms of the given pair values.

Now, we observe that:

R(2,99) = 2(2+99)+2 = 2*101 + 2 =204

R(4,46) = 4(4+46)+4 = 4*50 + 4 = 204

Accordingly, R(2,99) = R(4,46) = 204

Consequently, both the values are equal.
