It might help you

Step-by-step explanation:

1 man = 2 women

10 men + 8 women

= (20 + 8) women = 28 women

4 men + 6 women = (8 + 6) women

= 14 women

Given, M1=28,M2=14,D1=5,D2=?

and W1=W2=1

According to the formula,

M1D1W2=M2D2W1

=> 28×5×1=14×D2×1

D2=28×514=10days

Answer 2

Given:

Number of men =10

Number of women =8

Number of boys =6

Number of days for which they work =25

To Find:

how many days will 9920 women and 30 boys will be occupied with three times the eve of the work done in a particular time by a Man a Woman a boy are in the ratio 5 :3 : 2​

Explanation:

2 women = 1 man

8 women +10 men

= (20 + 8) women

= 28 women

Now for  4 men + 6 women

= (8 + 6) women

= 14 women

Forming the equation for the given question

we get,

M1=28,

M2=14,

D1=5,

D2=?

and W1=W2=1

According to the formula,

M1D1W2=M2D2W1

=> 28×5×1

=14×D2×1

D2=28×514

=10days

Answer - Number of days = 10Days.
