Question

4+7+2=281435 how to solve this question

Answer 1

To find 8+4+6

let no be a+b+c, on observation the right hand no. is concatenate of a*b, b*c and (a+b)*c in case of (a+b) < 9

or if (a+b)> 9 then

if =10 then a*b, b*c and (c)^2 if a>b or (c+1)^2 if a<b

if =11 then a*b, b*c and ((c+4)^2 -1)

if =12 then a*b, b*c and ((c+7)^2 -2) so,

8+4+6 = 3224168
