Question

One number is 3 times another number. If 15 is added to both the numbers, then one of the new numbers
becomes twice that of the other new number. Find the numbers.​

Answer 1

Let 1st number be x.

Then, 2nd number = 3x.

According to que,

3x+15=2(x+15)

3x+15=2x+30

x=15

Therefore, the two numbers are 15 and 45.

Answer 2

Answer:

x=3x

X+15=3x+15

according to question

2(X+15)=(3x+15)

2x+30=3x+15

X=15
