Question

Sum of 3 consecutive numbers is 90.. find no.

Answer 1

Solution:

Let the unknown number be x

1st number= x

2nd number= (x+1)

3rd number= (x+2)

Now, according to the question

x+(x+1)(x+2)= 90

3x+3= 90

3x= 90+3

3x= 93

x=93/3

x= 31

1st number= x= 31

2nd number= x+1= 31+1= 32

3rd number= x+2= 31+2= 33

Answer 2

let three numbers are
x
x+1
x+2
now sum of these numbers is equals to 90
x+x+1+x+2=90
3x+3=90
3x=90-3=87
x=87/3=29
so x=29
x+1=29+1
=30
x+2=29+2
=31
now sum of these numbers
29+30+31=90
