Question

If 10 people can build a wall in 30 days . How long will 15 people take to build the same wall?

Answer 1

Answer:

5

Step-by-step explanation:

this question is of inverse proportion

x*y=k

time taken to build the wall=30

wall was build by = 10 people

10*30=300

similarly

let the days in which the 15 men will complete the work be y

therefore

15*y=300

y=20

Answer 2

Answer:

20 days

Step-by-step explanation:

10 people = 30 days

15 people = (30 * 10)/15 days = 20 days
