Answer 2

572 parcels packed by 11 men a day.    

6:312::11:572

Step-by-step explanation:

Given:

6 men pack 312 parcels.

To find:

 Parcels are packed by 11 men a day.

Solution:

• The alikeness of the two ratios are meant to be as proportions.
• If a:b=c:d then we indicate that as a:b:: c:d, we say that a, b, c, d are alike with each other terms.
• we have a:b one ratio and c:d yet another ratio. we need to find the alikeness between the ratios.  
• ⇒$\frac{a}{b}$=$\frac{c}{d}$
• then, ad = bc  
• In this 6 men packed 312 parcels a day and we need to find out the parcels packed by 11 men a day.  

6:312::11:y

In the given data a=6, b=312, c=11 d we assume as 'y' d=y, Substituting the values in the formula we get,  

⇒ad=bc

⇒6y=312×11

⇒y= 312×11

          6

⇒y=52×11

⇒y= 572

d=y ,so we are substitute in the place of d=572, then

6 : 312 :: 11: 572

Thus we get 572 parcels are packed by 11 men a day    

Hence,

6:312 :: 11:572  

572  parcels packed by 11 men a day.
