Question

If 25 workers can complete a work in 48 days, then in how many days 20 workers will complete the same work?​

Answer 1

60 days

Explanation:

Thing to Remember

• Number of workers is inversely proportional to the number of days

Solving

• 25 men can do a certain amount of work in 48 days
• 25 men is reduced to 20 men ⇒ x 4/5
• Therefore, no. of days = inverse of rate of workers x 48
• ⇒ 5/4 x 48 = 5 x 12 = 60 days

Answer 2

heya! ^^

given that ,

25 workers together complete a certain piece of work in 48 days.

here , we've to find the number of days in which 20 workers can complete the same work ~

_____________________________

so let's start ~

★ 25 workers complete the work in = 48 days

★ 1 worker will complete the work in = 25 × 48 days

now ,

29 workers will complete the work in =
`\frac{\cancel{25} * 48} {\cancel{20}} \: \: days \\ \\ \dashrightarrow \: \frac{5 * \cancel{48}}{\cancel{4}} \\ \\ \dashrightarrow \: 5 * 12 \\ \\ \dashrightarrow \: 60 \: days`

hope helpful :D
