6 men can pack 12 boxes in 7 days by working for 7 hours a day. In how many days can 14 men pack 18 boxes if they work for 9 hours a day?Select one:a. 3.5 daysb. 12 daysc. 5 daysd. 7.5 days

Answer 1

Answer:

3.5 days

Step-by-step explanation:

If 'w1' work is done by 'm1' men by working for 'h1' hours per day in 'd1' days & 'w2' is work done by men 'm2' working for 'h2' hours per day in 'd2' days, then

(m1×d1×h1)/w1=(m2×d2×h2)/w2

Since we need to find 'd2', we can re-arrange the formula as, d2 =(m1×d1×h1×w1)/(m12×h2×w1)

=(6 x 7 x 7 x 18)/(14 x 9 x 12)

= 3.5 days
