Answer 1

The required answer is 90

Step-by-step explanation:

Persons required to finish the work in 15 days = 6

Answer 2

SOLUTION

GIVEN

6 persons can finish a piece of work in 15 days.

TO DETERMINE

The number persons can finish the work in 1 day

EVALUATION

Here it is given that 6 persons can finish a piece of work in 15 days

We solve it using as below by using Rule of Three

$\sf{ : \: \: \: \: \: \: \: \: \: Days \: \: \: \: \: \: \: \: \: \: \: Number \: of \: persons }$

$\sf{ : \: \:\: \: \: \: \: \: \: \: \: \: \: 15 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 6 }$

$\sf{ : \: \:\: \: \: \: \: \: \: \: \: \: \: 1 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ? }$

As the number of days decreases

The number of persons will be increased

The required number of persons

$\sf{} = 6 \times \dfrac{15}{1} \: \: \:$

$\sf{} = 90$
