প্রশ্নে বলা হচ্ছে, 2 জন পুরুষ এবং 3 জন নারী 3 দিনে একটি কাজের 14 অংশ করতে পারে। 3 দিন পরে ঐ দলে আরেকজন পুরুষ যোগ দিলে 2 দিনে তারা কাজের আরো 14 অংশ শেষ করলো। কতজন পুরুষ 4 দিনে ঐ কাজটি শেষ করতে পারবে?

2 man + 3 women, in 3 days complete 14 Portion

∴ 2 man + 3 women, in 1 days complete = 14 × 3 = 12 Portion

∴ Now, 3 men + 3 women, in 2 days complete = 14 Portion

∴ 3 men + 3 women, in 1 days complete = 14 × 2 = 18 Portion

∴ 1 man can complete in 1 day = 18- 112 = 3-224= 124 Portion of the work.

Now, 124 portion of the work is done in 1 day by 1 man

∴  1 (Complete) portion of the work is done in 1 day by = 24 ×11 man

∴  1 (Complete) portion of the work is done in 4 day by = 24 ×14 × 1 = 6  men
