Question

if the sum of two consecutive odd integers is 20, find the numbers.

Answer 1

let odd no be x
its consecutive odd no be=x+2
ATQ...................................=
x+x+2=20
2x+2=20
2x=18
x=9
odd no is 9 and its consecutive odd no is 11

Answer 2

Answer:

9,11 are two required consecutive odd integers

Explanation:

Let x, (x+2) are two consecutive odd integers.

According to the problem given,

Sum of two consecutive odd integers = 20

=> x+x+2 = 20

=> 2x + 2 = 20

Subtract 2 , both sides of the equation, we get

=> 2x+2-2 = 20-2

=> 2x = 18

Divide both sides by 2, we get

=> x = 9

Therefore,

Required Two consecutive odd integers are

x = 9 ,

x+2 = 9+2 = 11
