Three men or 6 women can do a job in 10 days. 3 men work

Solution

• 3 men OR 6 women can complete the work in 10 days

Let’s express the total work in man-days or woman-days :

• 3 men × 10 days = 30 man-days
• 6 women × 10 days = 60 woman-days

So,

• 1 man = 2 women in work efficiency

Calculate Work Done by 3 Men in 7 Days

• Work = 3 men × 7 days = 21 man-days

Since 1 man = 2 women, → 21 man-days = 42 woman-days of work completed. Remaining Work Total work (in woman-days) = 60 Work done = 42 Remaining work = 18 woman-days Women Needed to Finish Remaining Work in 6 Days We want to complete 18 woman-days of work in 6 days , so: Women required} = 18/6 = 3 Option D. 3
