Question

4. 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

Answer:

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 number be x and 3x

then x=3x

atq

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

2x+30=3x+15

30-15=3x-2x

15=x

one number is 15 and other is 45
