Question

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

Answer 1

Let the numbers be ( x - 1 ) , ( x ) , ( x + 1 )

Given that, x - 1 + x + x + 1 = 156

3x = 156

x = 156 / 3

x = 52

Therefore the other numbers are : ( x - 1 ) = 52 - 1 = 51 ; ( x + 1 ) = 52 + 1 = 53

All the three numbers are 51, 52, 53, out of which 52 is a multiple of 13.

Answer 2

Here is your solution

Given :-

The sum of three consecutive numbers is 156

Let consecutive number be x ,x+1,x+2

A/q

=>x+(x+1)+(x+2)= 156
=>3x+3=156
=>3x=156-3
=>3x = 153
=>x=51

The three consecutive numbers is

x = 51

x +1 = 51+1 = 52

x+2 = 51+2 = 53

The three consecutive numbers is 51,52,53

Hence

52 is multiple of 13✔
