Question

1. A number is 21 lesser than the other. Find the numbers if their sum is 29.
2. The sum of three consecutive numbers is 243 Find the​

Answer 1

Answer:

1. 50-21=29

2. Since the numbers are consecutive,

x+x+1+x+2= 243

3x+3= 243

3x= 243-3

= 240

x= 240/3

x= 80

So,

x+1= 80+1= 81

x+2= 80+2=82.

Hope you find it helpful.

Answer 2

Step-by-step explanation:

1.Let the number be x

Then, other number = x-21

Given, their sum = 29

= x+x-21=29

= 2x=29+21

= 2x= 50

=x= 50/2

=x=25

The numbers are: x= 25 ; x-21 = 25-21 = 4

2.Let the three consecutive be x,x+1x+2

Given,sum of three consecutive numbers =243

=x+x+1+x+2=243

=3x+3=243

=3x=243-3

=3x=240

=x=240/3

=x=80

So, three consecutive numbers are:x=80; x+1=80+1=81 ; x+2 =80+2 = 82
