Answer :

2 জন পুরুষ ও 5 জন মহিলার একটি দল 3 দিনে একটি কাজের 1/4 অংশ করল। 3 দিন পরে, আর একজন পুরুষ ঐ টিমে যোগ করলেন এবং তারা একত্রে 2 দিনে আরো 1/4 অংশ কাজ করল। কত জন পুরুষ 4 দিনে কাজটি করতে পারবে?

2 men and 5 women require 3 days to complete $\frac{1}{4}$ job

∴ They complete $\frac{1}{4 \times 3} = \frac{1}{12}$ job in 1 day.

3 men + 5 women require 2 days to complete $\frac{1}{4}$ job;

∴ They complete $\frac{1}{4 \times 2} = \frac{1}{8}$ in 1 days.

$\frac{3 m e n + 5 w o m e n = \frac{1}{8} 2 m e n + 5 w o m e n = \frac{1}{12}}{(S u b t r a c t i n g) 1 m a n = \frac{1}{8} - \frac{1}{12} = \frac{3 - 2}{24} = \frac{1}{24}}$

$\frac{1}{24}$ job is done in 1 day by 1 men

∴ 1 job is done in 1 day by 24 men

∴ 1 job is done in 4 day by $\frac{24}{4} = 6$ men
