We use the concept given below,

If M

1

workers earn Rs.R

1

in d

1

days, then M

1

×d

1

workers earn R

1

,Rs in 1 days then

R

1

M

1

×d

1

earn 1 Rs in 1 days

If M

2

workers earn Rs.R

2

in d

2

days then

R

2

M

2

×d

2

earn 1 Rs in 1 days

Hence in 1 day, Rs. 1 earned by

R

1

M

1

×d

1

=

R

2

M

2

×d

2

Now we use that formula we Find the solution of the equation

Let M

1

=5

R

1

=9000 Rs

d

1

=15 days

and M

2

=x,R

2

=6720 Rs

and d

2

=8 boys

9000

15×15

=

6720

x×8

x=

9000

6720×5×15

=7 labourers
