Question

the sum of three consecutive numbers is 156. find the number which is multiple of 13 out of these numbers.

Answer 1

let x, x+1,x+2 be the consecutive numbers

their sum is 156

x+x+1+x+2=156

3x+3=156

3x=153

x=51


so the numbers are 51,52,53


52 is the multiple of 13



I hope this will help u ;)

Answer 2

Heya!!

Let's take one integer as x.

We know that, the consecutive one would obviously be x+1 and x+2

So the three numbers are x, x+1 and x+2.

Now, We know that they sum up to 156. Hence,

x+ x+1+ x+2=156
3x+3=156
3x=153
x=51

So the Consecutive integers will be 51, 52, 53 (x+1 and x+2)

Now that we have to find a number 'divisible' by 13. It is easy, We already know 52 is exactly divisibly by 13.

And there you go! The answer is 52

Hope it helps! :)
Have a great day
