Answer 1

Answer:

4)the sum of two consecutive numbers is 56?

so lets think the first number as x

and second number as x+1

x+x+1=56

=2x+1=56

x+1=56/2

x+1=28

x=28-1

=27

so the 2 numbers are 27,29

5)x,x+7,x+14=777

=3x+21=777

=3x=777-21

3x=756

x=765/3

=255

second number is x+7=255+7=262

third number is x+14=255+14=269

6)the walking distance of the man is 10 kms

the total distance is 70 kms

if we subtract walking distance from total distance=70-10=60kms

60 kms is the distance the man travels in both bus and train

he travels twice distance by bus than by the train

let the distance travelled by trai as x

so the distance travelled by bus as 2x

=x+2x=60

=3x=60

x=60/3

x=20

the distance travelled by train is 20 kms

the distance travelled by bus is 2x =2*20=40kms

7)let the first piece as x

the second piece as x+7

the third piece as x-4

x+x+7+x-4=300

3x-3=300

3x=300-3

3x=297

x=297/3

=99

the weight of first piece is 99

the weight of second piece is x+7=99+7=106

the weight of third piece is x-4=99-4=95
