 <translate> A's one day's work = 1/30
B's one day's work = 1/45
(A + B)'s one day's work = 1/30 + 1/45 = 1/18
The part of the work completed in 2 days = 2 (1/18) = 1/9.
The final answer: (D). <yor> A jẹ́ iṣẹ́ ọjọ́ kan = 1/30 B jẹ́ iṣẹ́ ọjọ́ kan = 1/45 (A + B) jẹ iṣẹ́ ọjọ́ kan = 1/30 + 1/45 = 1/18 Apá iṣẹ́ tí wọ́n parí ní ọjọ́ méjì = méjì (1/18) = ìkíní sí mẹ́sàn-án. Ìdáhùn tó péye: (D).
