### Instruction:
 Armand anacheza mchezo wa kubashiri na baba yake ambapo anapaswa kubashiri nambari ambayo baba yake anafikiria. Baba yake anamwambia kuwa nambari hiyo, ikiongezwa mara tatu, ni tatu chini ya mara mbili ya 51. Nambari ni ipi?


### Response:
 Maradufu ya 51 ni 51*2=<<51*2=102>>102
Tatu chini ya mara mbili ya 51 ni 102-3=<<102-3=99>>99
Nambari hiyo, ikiongezwa mara tatu, inakuwa 99/3=33
