Answer 1

30 men One day's work = 1 / 10
1 man One day 's work = 1 /( 10 x 30 ) = 1 / 300
40 men One day's work = 40 x ( 1 / 300 ) = 40 / 300
Work Completed by 40 men in 10 days
= 300 / 40 ( Reciprocal of 40 / 300 )
= 30 / 4
=( 30 / 4 ) x ( 25 / 25 )
= ( 30 x 25 ) / ( 4 x 25 )
= 750 / 100 = 7.50

Answer 2

Answer:

Step-by-step explanation:

30 men One day's work = 1 / 10

1 man One day 's work = 1 /( 10 x 30 ) = 1 / 300

40 men One day's work = 40 x ( 1 / 300 ) = 40 / 300

Work Completed by 40 men in 10 days

= 300 / 40 ( Reciprocal of 40 / 300 )

= 30 / 4

=( 30 / 4 ) x ( 25 / 25 )

= ( 30 x 25 ) / ( 4 x 25 )

= 750 / 100 = 7.50
