Question

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

Answer 1

Hii friend,

Let the one Number be X.

Then the other number = 3X

Five is added to both the numbers then the numbers becomes (X+5) and (3X+5)

According to question,

3X +5 = 2(X+5)

3X +5 = 2x +10

3X-2X = 10-5

X = 5.

Therefore,

One Number = X = 5

And,

The other number = 3X = 3 × 5 = 15

HOPE IT WILL HELP YOU.... :-)

Answer 2

Answer:

let one no. be x

and another no. be 3x

x+15=3x+15

2(x+15)=3x+15

30-15=3x-2x

15=x

the first no. x=15

another no.3x=15×3=45
