 <translate> (1 man + 1 woman)’s 1 day work = 1/3 + 1/4 = 7/12
Work done by 1 man and 1 women in 1/4 day = ((7/12) x (1/4)) = 7/48
Remaining work = 1 - 7/48 = 41/48
Work done by 1 boy in 1/4 day = ((1/12) x (1/4)) = 1/48
Therefore, Number of boys required = ((41/48) x 48) = 41 Final answer: (A). <yor> (Ọkùnrin kan àti obìnrin kan) = 1/3 + 1/4 = 7/12 Iṣẹ́ tí ọkùnrin kan àti obìnrin kan ṣe ní 1/4 ọjọ́ = ((7/12) x (1/4)) = 7/48 Iṣẹ́ tó kù = 1 - 7/48 = 41/48 Iṣẹ́ tí ọmọkùnrin kan ṣe ní 1/4 ọjọ́ = ((1/12) x (1/4)) = 1/48 Nítorí náà, Iye àwọn ọmọkùnrin tí a nílò = ((41/48) x 48) = 41 Ìdáhùn tí ó kẹ́yìn: (A).
