IN second case.. B*O=O {2 possibilities either O=5 or B=6 then only it will give same no.}
Lets say B=6 then O={2,4,8} but in other cases like 1. if B=6 then B*B should have given result as B {i.e, 6*6=36} but this is not so
Therefore, O=5;
Put everywhere O=5
now B=odd that's why we get O {5* odd= _5 }
B=3,7,9 ( B~=1 refer case 1)
put B=3

E=0,Y=9;
so we get..
M= 1, ?=7,L=6 ,O=5,B=3,E=0,Y=9; - 6 years agoHelpfull: Yes(2) No(1)
- step 1:check B*0 = O => O = 5
STEP 2: B = (1,3,5,,7,9)
this is so that 0 can have its unit digit as 5
take B values 1 by 1, the correct value will be B = 3
this will eventually lead to the correct solution
final result:
