if 8 labourers can earn rs.9000 in 15 days.how many laboures can earn rs. 6300 in 7 days?
1 labour-day = 9000/(8*15) = 75
So to earn 6300 would take 6300/75 = 84 labour days
so the number of labourers to work 7 days = 84/7 = 12
Labourers earning days
8 9000 15

So 1 day = 9000/(8*15) =75
To earn 6300 = 6300/75=84
No of labourers to work 7 days
Is 84/7= 12.
Thank you
ATQ,
Earning of 8 labourers in 1 day=9000/15=₹600
Earning of 1 labourer in 1 day=600/8=₹75
Earning of 1 labourer in 7 days=₹75*7=₹525
So,
₹525 can be earned in 7 days by-1 labourer
₹6300 can be earned in 7 days by-6300/525=12 labourers

Such a great explanation
To find out how many laborers can earn Rs. 6300 in 7 days, we can use the concept of direct proportion.
Let's assume that x laborers can earn Rs. 6300 in 7 days.
According to the given information, 8 laborers can earn Rs. 9000 in 15 days.
To establish a proportion, we can write:
8 laborers / Rs. 9000 = x laborers / Rs. 6300
To solve this proportion and find the value of x, we can cross-multiply:
8 * Rs. 6300 = Rs. 9000 * x
50400 = 9000x
Now we can solve for x by dividing both sides of the equation by 9000:
50400 / 9000 = x
x = 5.6
Since you cannot have fractional laborers, we can round this number down to the nearest whole number. Therefore, approximately 5 laborers can earn Rs. 6300 in 7 days.
