Question

The sum of three numbers is 84
The second number is 2 times the first
The third number is 16 less than the second
What is the second number?

Answer 1

Answer:

second number is 40

Step-by-step explanation:

let the first number be x

second is 2 times the first number

therefore it's 2x

3rd number is 16 less than second

therefore it's 2x-16

now

x+2x+2x-16=84

5x=100

x=20

second number is 2x

= 2*20

=40

Answer 2

Answer:

So let the first no. be x; second no. be 2x and third no. be 2x-16

Now, x+2x+(2x-16) =84

5x-16=84

5x=100

x=20

So the second no. is 2x=40
