Question

2. A positive number is 5 times another number. If 21 is added to both the numbers, then one of the new numbers becomes twice the other new number. What are the numbers? ​

Let another number be x.

Then positive number = 5x

According to the question, 5x+21=2\left(x+21\right)

5x+21=2x+42

5x-2x=42-21

3x=21

=21/3=7

Hence another number = 7 and positive number = 7 x 5 = 35.

Answer 2

Step-by-step explanation:

SOLUTION :

Let the first number = x

Then the second number = 5x.

Now the question states that if we add 21 to both numbers one number becomes twice of the other.

i.e., 2(x + 21) = 5x + 21

or 2x + 42 = 5x + 21

Transposing 2x to the RHS and 21 to the LHS:

21 = 5x - 2x = 3x

or x = 7

Thus the two numbers are 7 and 35 . (Since second no. = 5x)
