Question

5 ladies can complete a work in 14 days and 5 kids take 28 days to complete the work. How many days will 10 ladies and 5 kids take to complete the work?

• A. 3.5 days
• B. 6.3 days
• C. 5.6 days
• D. 8.4 days
• E. 4.9 days

Answer 1

The correct option is C

5.6 days

Work done by a lady in one day = $\frac{1}{70}$

Work done by 10 ladies in one day = $\frac{1}{7}$

Work done by a kid in one day = $\frac{1}{140}$

Work done by 5 kids in one day = $\frac{1}{28}$

Time taken to complete the work = 5.6 days
