Read Solution (Total 8)
-
- ans- 7
let digits of no. be x nd y i.e xy
as x^2+y^2=50 nd x>y
for x=7 nd y=1 both condition satisfied
so 7*1=7 - 11 years agoHelpfull: Yes(7) No(1)

so it may maximum be
71 since leftdigit greater than right - 11 years agoHelpfull: Yes(0) No(0)
- 1^2+2^2#50
1+9#50
.........
1+49=50
=>no. is 71
=>highest product=7 - 11 years agoHelpfull: Yes(0) No(0)
