Question

4.40 persons take 30 days to complete a work. How long will it take to complete the work. If
20 more persons join them?​

Answer 1

Answer:

Time Taken By 4.40 persons = 30 days

Therefore time taken by 1 person = 30 ÷ 4.40

If 20 more persons join then,

Therefore time taken by 24.40 persons =

$\frac{30 \times 100}{440} \times \frac{2440}{100} = > \frac{30 \times 244}{44}$

=> 166.36
