- @ vineysagar
there are few tricks by which u can solve crpt like
1 * n = n,0 * n = 0,
5*odd no = x5 ,where x can be 0,1,2,3,4
6*even no=(y)even no, where y can be 1,2,3,4
these are the only trick which i know - 10 years agoHelpfull: Yes(2) No(1)
- sorry it's T * K=K in place of O * K=K

- t*k=k
so pair of (t,k) are (6,4),(7,5),(9,5)(3,5)
try with these pair one by one
finally
with (7,5)

Explanation:-
(1)T=O+1(because sum of any distinct 2 digit no. is not>=20)
(2) t*k=k therefore,either t=6,K=any even no.(except 6) or k=5
so, if you take t=6 then O=5 therefore possible values of k=2,4,8
taking all the possible values of k it will not satisfy R+K=5.
NOW, take k=5 , possible values of (T,O)={(3,2),(7,6),(9,8)} - 10 years agoHelpfull: Yes(1) No(0)
- @tulsi Can u pls explain

- In the 4th line if we see , O * K =K may have two possibilities either T=1 (1*n=n) or K=5(5*odd no=_5),but T can't be equal to 1 because if it would be 1 then the 4th line would be like ASK but according to question OSAK is given.therefore K will 5.now if K will be 5 then O will be an even no and L will be 0(because 5*even no=_0).Now O can be (2,4,6,8) and T can (3,7,9).from the last row also we get O+1(carry)=T............from these information you can find all other values.
