Question

22 men can complete a job in 16 days in how many days will 32 men complete that job

Answer 1

Answer:

11 days

Step-by-step explanation:

work = days*men  => 22 * 16 =352 ---> (i)

same work should be completed by 32 men in (x) days

work = 32x

from (i)  32x = 352   => x =352/32 = 11

Alternative method :

22 men do the job in 16 days

i.e   22:16

32 men do the job in (x) days

i.e   32:x

Calculation:   $\frac{22}{32}$ = $\frac{16}{x}$

Note that man days are a special case ,therefore we take the reciprocal of either 22/32 or 16/x

i.e  $\frac{32}{22}$  = $\frac{16}{x}$   =>  x =$\frac{16 * 22}{32}$ = 11
