Question

The sum of three numbers is 90 the second number is five more than the first and the third exceeds the first by 10 find the number

Answer 1

Answer

Let the number be x.

Now,

x,x+5,x+10

x+x+5+x+10=90

3x+5+10=90

3x+15=90

3x=90-15

3x=75

x= 75/3

x= 25

Hence, The first number = 25

The second number = 25 +5 =30 (x+5)

The third number = 25 +10=35 (x+10)
