1.

if the product of the digits of a two digit number is twice the sum of the digits of that number then that number is___.(22,44,66)​

Answer»

Answer:

Let the tens DIGIT of the REQUIRED number be x and the units digit be y. Then,

x+y=12  

Required Number = (10x+y).

Number OBTAINED on reversing the digits = (10y+x).

Therefore,

(10y+x)−(10x+y)=18

9y−9x=18(2)

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

2y=14⟹y=7

Therefore,  

x=5

Hence, the required number is 57.
