In a two digit number the digit in the unit's place is twice the digit in the ten's place and the number obtained by interchanging the digits is more than the original number by 27. What is 50% of the original number? = 12 x = 12×3 = 36

Answer 2

Answer:

15

Step-by-step explanation:

ten's place digit number be y

Then, unit's digit number is 3y + 2 [we write 3'y' because the tens place = y]

The sum of the two numbers in 6, Hence,

y + 3y + 2 = 6

4y = 6 - 2

4y = 4

y = 4/4 = 1    [ y = 1 ]

Therefore: unit's place digit is 3y + 2 = 3 × 1 + 2 = 5

Ten's place digit is y = 1.  

The number is 15.
