Question

In a two digit number the digit in the ten's place is three more than the digit is the unit's place. Two times the digit is the unit's place is equal to the digit is the ten's place. Find the number

Answer 1

Answer:

63

Step-by-step explanation:

Let the number in the units place be x and the number in the tens place be y.

So, the number is yx.

According to the question,

y = x + 3    ........i

2x = y        ........ii    

Using y = 2x in (i)

 2x = x + 3

⇒2x - x = 3

⇒       x = 3

Using x = 3 in (ii)

y = 2 * 3

y = 6

∴The number is yx = 63.
