Answer 1

Step-by-step explanation:

if 52 men do the work by 35 days

1 man= 52÷35

then multiply the answer by 28.

Answer 2

Step-by-step explanation:

5. The number of men doing a work and the number of days taken are in inverse proportion.

Let the number of days taken by 28 men be a

Then, 35:a:: inverse ratio of 52:28

=>35:a=28:52

Applying the rule, product of extremes = product of means

35×52=a×28

a= 35×52 / 28

a=65

Hence, 28 men can do the work in 65 days.

6. 1 000 soldiers + 500 soldiers = 1 500 soldiers

1 000 / 1 500 = 500 * 2 / ( 500 * 3 ) = 2 / 3

( 2 / 3 ) * 36 = 72 / 3 = 24 days

OR

Camp has enough food to feed 36 000 soldiers for 1 day.

36 000 / 1 500 = 24 days
