Given:
3*2 = 29 -- equation (1)
4*5 = 74 -- equation (2)
7*3 = 58 -- equation (3)
We can write equation (1) & (2) as,
(3 + 2) x 6 - 1 = 29
And
(4+5) x 8 + 2 = 74
In the same way,
(7 + 3) x 6 -1(2) = 58 [ They are doubled this time].
Hence, 6*8 can be written as,
(6 + 8) x 8 + 2(2)=14 * 8 + 4= 112 + 4
6 x 8 = 112.
Hence, the value of 6x8 is 116.
