Question

A positive number is 5 times another number if 12 is added to both the numbers,then one of the new numbers becomes twice the other new number.what are numbers?​

Answer 1

Answer:

Let the No.1 = x

Then the second no. No.2 = 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 No.2 = 5x)

Answer 2

Step-by-step explanation:

Solution :

let first number be 5x<br> other number will be x<br> According to question<br> (5x+21)=2(x+21)<br> 5x+21=2x+42<br> 3x=21<br> x=7<br> 5x=5*7=35<br> First number is 7 and other number is 35.
