Answer 1

Answer:

Answer is 25

Step-by-step explanation:

12 person can finish work in 15 days

So 20 person can finish work in x days

So by condition

12 / 15 = 20 / x

4 / 5 = 20 / x

4x = 100

x = 25

So 20 person can finish work in 25 days

Answer 2

Answer:

25 days

Step-by-step explanation:

Let the days took by 20 Person be x

12 Person = 15 days

20 Person =  x days

Cross Multiplication

15×20 / 12 × x

x = 15 × 20 / 12

Cancellation

x = 5 × 10 / 2

x = 50 / 2

x = 25

Therefore it takes 25 days for 20 person to finish the same work.
