sorry,, i forgot to count that two 5's in 25 and 50. so min is 55 and max is 59

spandana inti  (11 years ago)

min is 65 and max is 69
in order to get 13 zeroes we need 13 5's and 2's
is enough if we see that we get 13 5's bcz the number of 2's will anyways be more!
5 is there in 5,10,15,20,...,65. so min 13 5's till 65.. to get max we shud see that we dont get another 5 i.e it should be less than 70. so max will be 69.

5*2,15*12,25*22,35*32,45*42,55*52
10,20,30,40,50,60. Till now 12 zeros.
The one zero which is left is-25 has two 5s.. i.e 25=5*5.So one 5 will pair up with 22 as mentioned above and one 5 will make another zero with 24(as 5*4=20).
So you need minimum 60! and max it could be 64!
