Answer 2

25 men are required to type 5400 pages working 4 hour per day for 3 days.

Step-by-step explanation:

15 men can type 3240 pages in 6 days working 2 hours per day

Let $M_1$ be the no. of men , $D_1$ be the no. of days , $H_1$ be the no. of hours and $W_1$ be the no. of pages in case 1.

$M_1=15\\D_1=6\\H_1=2\\W_1=3240$

We are supposed to find  How many men are required to type 5400 pages working 4 hour per day for 3 days?

Let $M_2$ be the no. of men , $D_2$ be the no. of days , $H_2$ be the no. of hours and $W_2$ be the no. of pages in case 2

$M_2=?\\D_2=3\\H_2=4\\W_2=5400$

ATQ

$\frac{M_1 \times H_1 \times D_1}{W_1}=\frac{M_2 \times H_2 \times D_2}{W_2}\\\frac{15 \times 2 \times 6}{3240}=\frac{? \times 4 \times 3}{5400}\\\frac{15 \times 2 \times 6 \times 5400}{3240\times 4 \times 3}=?\\25 = ?$

Hence 25 men are required to type 5400 pages working 4 hour per day for 3 days.
