 <translate> Work done by A in 3 days = 3/5
Remaining work = 2/5
Work done by both A and B in one day = 1/5 + 1/10 = 3/10
Remaining work = 2/5 * 10/3 = 4/3 days. So the final answer is (A). <yor> Iṣẹ́ tí A ṣe ní ọjọ́ mẹ́ta = 3/5 Iṣẹ́ tó kù = 2/5 Iṣẹ́ tí A àti B ṣe lọ́jọ́ kan = 1/5 + 1/10 = 3/10 Iṣẹ́ tó kù = 2/5 * 10/3 = 4/3 ọjọ́. Nítorí náà ìdáhùn tí ó kẹ́yìn ni (A).
