11 carpenters working 5 hours day complete a furniture work in 16 days .How long would it take for 12 carpenters working for 2 hours per day to complete the same piece of work

Answer: 37 days

SOLUTION 1 :

Number of carpenters	Number of hrs	Number of days
11	5	16
12	2

Number of carpenters increases from 11 to 12.The Number of days decreases.

It is in inverse variation.

The multiplying factor = $\frac{11}{12}$

Consider the number of hrs for days & the number of days. as the number hrs decresesï»¿ from 5 to2 . The number of days increases.

It is in inverse variation.

The multiplying factor = $\frac{5}{2}$

x = ( $\frac{11}{12}$ ) x ( $\frac{5}{2}$ ) x 16

=(0.92 x 2.50 x 16)

= 37 days
