Question

12 people can build the wall in 20 hours.how many people will be required to build the same wall in 15 hours.

Answer 1

$\frac{12 \times 20}{15}\ is\ the\ answer.\ Because\ time\ taken\ to\ build\ and \\ no.\ of\ people\ built\ are\ inversely\ proportional. \\ \\ \frac{12 \times 20}{15} = \frac{4 \times 20}{5} = 4 \times 4 = \bold{16} \\ \\ \therefore\ \bold{16}\ people\ will\ be\ required\ to\ build\ the\ same\ wall\ in\ 15\ hours. \\ \\ \\ Thank\ you. \\ \\ \\ \#adithyasajeevan$

Answer 2

Dear Student,

● Answer -

16 people are required

● Explanation -

Let x be no of people required to build the same wall in 15 hours.

12 × 20 = x × 15

240 = x × 15

x = 240 / 15

x = 16 people

Hence, 16 people are required to build the same wall in 15 hours.

Thanks dear for asking. Hope this is helpful to you...
