Answer 2

Step-by-step explanation:

let , x and y be the two numbers .

then,

original number = 10x+y. ( 1)

after adding 15 in original number then the number be,

final number = 10x+y + 15 (2)

now, according to the question,

3(10x+y) = 10x +y +15

or, 30x +3y = 10x +y+15

or,20x +2y = 15

or,10x +y = 15/2

now, putting value of 10x+y = 15/2 in equation 1 we get

10x+y = 15/2 which is the required answer .
