Answer:

HI mate.....

your answer is 10/7

Step-by-step explanation:

mens days

4. 5.

3. 7.

so, it is inverse variation.

boys days

6. 5.

4. 7.

so, it is also inverse variation.

now, to find the number of days taken for 4,3 mens and 6,4 boys to finish the work

=inverse variation

=4/3*6/4

=2.

number of days =2

so, for 1 man or boy,

=5/7 /2

5/7*2/1

=10/7.

so, 1 man or boy will be taking 10/7 days to finish the work.
