Answer 1

Answer:

Step-by-step explanation:

Let earning of 1 boy in 1day =Rs.x

now,8×[{(14×6)/4}+(10×2)+14]x=Rs.9900..

55x=990

so,x=5

Earning of 8men and 6women in 1day

={8×(7/4×10)}+{6×10}=140+60=200

so,In 10days= Rs.200×10 =Rs.2000

Answer 2

Answer:

Step-by-step explanation:Given : 4 men earn as much as in a day as 7 women one women earn as much as two boys if 6 men and 10 women in 14 boys work together for 8 days to earn 2200 then what will be the earning of 8 men 6 women working together for 10 days​.

Let earning of one boy in one day be Rs p

So now 14 x 6 /4 = 84 / 4 = 21 and 10 x 2 + 14 = 34

21 + 34 = 55

Now 55 x 8 p = 2200

440 p = 2200

P = 2200/440

P = 5

Now we need to find earning of 8 men and 6 women in 1 day

= 8 x 7/4 x 10 = 140 + 6 x 10 = 140 + 60 = 200

In one day earning will be Rs 200

So for 10 days it will be 200 x 10 = Rs 2000
