4 men and 3 women finish a job in 6 days
4 men and 3 women finish a job in 6 days, and 5 men and 7 women can do the same job in 4 days. How long will 8 men and 6 women take to do the same job?
4 पुरूष और 3 महिलाएँ एक कार्य को 6 दिनों में पूरा करते हैं, तथा 5 पुरूष और 7 महिलाएँ उसी कार्य को 4 दिनों में पूरा कर सकते हैं। 8 पुरूष और 6 महिलाएँ उसी कार्य को पूरा करने में कितना समय लेंगे?
Detailed Solution & Logic
Correct Answer:
3 days / 3 दिन
(4m+3w)6=(5m+7w)4
24m+18w=20m+28w
$ m=\dfrac{5}{2} $w
Work =78 w
8m+6w=26w
Time=$ \dfrac{78w}{26w}=3 $
3 days / दिन
