Answer 2

The answer is 22 boys

Given:

5 boys take 7 hours to pack 35 cartoons

To find:

How many boys can pack 65 cartoons in 3 hours?

Solution:

Given for 5 boys it took 7 hrs to pack 35 cartoons  

Note:

If a work 'w₁' is done by 'm₁' in hrs 'h₁' and work 'w₂' is done by 'm₂' men in hrs 'h₂' then

                           m₁h₁/w₁ = m₂h₂/w₂

From given data,

m₁ = 5, h₁ = 7, w₁ = 35 and h₂ = 3 and w₂ = 65  

Let m₂ = x

⇒ 5(7)/35 = x(3) /65

⇒ 65(5)(7) = x(3)(35)

⇒ 65 = 3x

⇒ x = 65/3

⇒ x = 21 2/3    

Here we can't say 21 2/3 boys

⇒ The answer is 22 boys
