Three times the first of three consecutive odd integers is 3 more than twice the third. The third integer is:
Answer: Option
Explanation:
Let the three integers be x, x + 2 and x + 4.
Then, 3x = 2(x + 4) + 3 
x = 11.
Third integer = x + 4 = 15.

Zero is neither odd nor even number.

If we put x=1,then three consecutive no's x,x+2,x+4 gets an odd no.

Forget everything just go option wise then answer should be 9 or 15.

Three consecutive integers x, x+1, x+2
3x=2(x+2)+3
x=7
x+2=9
3x=2(x+2)+3
x=7
x+2=9

In this problem, they had given three consecutive odd integers.
If we take that 3 odd integers as x , x+2 and x+4,
if we put x = 2 => the numbers will become 2 , 4, 6
these nos are even numbers..then how we assume X,X+2,X+4 as three consecutive odd integers?
Can anyone Clear my doubt??

Rahman is right.
Because the given numbers should be odd numbers.
So we have to take...the three consecutive odd numbers as 2x+1, 2x+3, 2x+5

2x+1, 2x+3, 2x+5
3(2x+1)=2(2x+5)+3
... x=5
(2x+5)=15
3(2x+1)=2(2x+5)+3
... x=5
(2x+5)=15

The first part is 3 more than the second part.
So to equate it we have to add 3 to the second part
I part = II part + 3
The ans 15 is correct
