ഇവിടെ, പിന്തുടർന്ന ക്രമം ഇതാണ്,

43 → 4 + 3 = 7 (അഭാജ്യ സംഖ്യ)

38 → 3 + 8 = 11 (അഭാജ്യ സംഖ്യ)

58 → 5 + 8 = 13( അഭാജ്യ സംഖ്യ)

64 → 6 + 4 = 10 (അഭാജ്യ സംഖ്യ അല്ല)

89 → 8 + 9 = 17 (അഭാജ്യ സംഖ്യ)

64 ഒഴികെ എല്ലാ അക്കങ്ങളുടെയും ആകെത്തുക ഒരു അഭാജ്യ സംഖ്യയ്ക്ക് തുല്യമാണ്.

അതിനാൽ, '64' ആണ് ശരിയായ ഉത്തരം.
