 
 <translate> The question is: How many zeroes are there at the end of the number N, if N = 100! + 200! ?
Options:
(A) 73
(B) 49
(C) 20
(D) 48
(E) 24
Stream of consciousness: The number of zeroes at the end of 100! will be less than the number of zeroes at the end of 200!
Hence it would be sufficient to calculate the number of zeroes at the end of 100!
Number of zeroes = [100/5] + [100/25] + [100/125] = 20 + 4 + 0 = 24
 <hau> Tambayar ita ce: Nawa ne sifili a ƙarshen lambar N, idan N = 100! + 200!? Zaɓuɓɓuka: (A) 73 (B) 49 (C) 20 (D) 48 (E) 24 Tsarin hankali: Yawan sifili a ƙarshen 100! zai zama ƙasa da adadin sifili a ƙarshen 200! Saboda haka zai isa a lissafa adadin sifili a ƙarshen 100! Yawan sifili = [100/5] + [100/25] + [100/125] = 20 + 4 + 0 = 24
