Answer:

hello  dear ,

Step-by-step explanation:

So from case 1 we can say that no would be 27 as adding 45 to it make it reverse,I.e. 72. A two digit number is such that the product of the digit is 12. When 36 is added to the number, the digits interchange their places.

Answer 2

Answer:

The required no. is 27

Explanation :

Let the ten’s place digit be x.

And the unit’s place digits be (14/x).

Therefore the number formed

= (10x + 14/x)

According to the Question :

= 10x + 14/x + 45 = 10 × 14/x + x

= x² + 5x - 14 = 0

= (x+ 7)(x - 2) = 0

= x = - 7, 2 (Neglecting negative sign's one)

= x = 2

Number = (10x + 14/x)

= (10 × 2 + 14/2)

= 27

Therefore the required number is 27.

Hope it helps :) ❤
