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, 3*x* = 2(*x* + 4) + 3 *x* = 11.

Third integer = *x* + 4 = 15.

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

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

Zero is neither odd nor even number.

Hey can anyone explain this problem? I don't understand these "odd integers is 3 more than twice the third".

Hi all,

1> See it is said that first of 3 consecutive odd no is 3.

2> It is said 3 times the first no means i.e. 3*3 = 9.

3> It is also said that 3rd no is 3 more or twice the first i.e. 6.

4> That's how we get the answer 9+6=15.

1> See it is said that first of 3 consecutive odd no is 3.

How we take x, x+2, x+4 are odd integers if we take x=2 then it become even can any one clear this doubt ?

As they hav given 3 consecutive odd integers then that 3 can be assumed as 2x+1,2x+3,2x+5 ...

because x,x+2,x+4 wont give us odd values if v substitute any positive integers. then the values which i have assumed can satisfy all consecutive odd integers so now

1st of 3 consecutive integers is 2x+1

so now 3*(2x+1)=3+(2*(2x+5)

=> 6x+3=4x+13

=> x=5

now 3rd integer is

2x+5

=> 2(5)+5=15.

1st of 3 consecutive integers is 2x+1

so now 3*(2x+1)=3+(2*(2x+5)

=> 6x+3=4x+13

=> x=5

now 3rd integer is

2x+5

=> 2(5)+5=15.

Hi,

Consecutive nos are x, x+2, x+4. If we add 1 to these nos we get odd consecutive nos.

So read the question neatly.

3 times the first of three consecutive nos it means first consecutive no is x. 3 times means 3x.

So answer is 15.
