Answer 1

Answer:

79

Step-by-step explanation:

Let the tens digit of the required number be x and the units digit be y.

Then,

x + y = 16   ---- (1)

Required number = 10x + y

Number obtained on reversing = (10y + x)

Therefore,

(10y + x) -(10x + y) =  18

⇒ 10y + x - 10x - 10y = 18

⇒ y - x = 2   ------ (2)

On adding (1) and (2), we get

x + y = 16

-x + y = 2

-----------------

    2y = 18

     y = 9

Place y = 9 in (1), we get

x + y = 16

⇒ x + 9 = 16

⇒ x = 7

Therefore,

Required number = 79

Hope it helps!
