Question

one number is three times another number if 15 is added to both the numbers one of the new numbers becomes twice that of the other now new number find the number

Answer 1

Answer:45

Step-by-step explanation:

Let the one of the no be x

And other no is n

Then, x=3n

n=x/3

New no are

x+15

And

x/3+15

Then, x+15=2(x/3+15)

=> x+15=2x/3+30

=> x+15-30=2x/3

=> x-15=2x/3

=> x-2x/3=15

=> (3x-2x) /3=15

=> x/3=15

=> x=15*3

=> x=45
