Answer 1

Answer:

=> 48

Step-by-step explanation:

=> Let the ten's place digit be x and one's place digit be y .

=> Thus the number is (10x + y)

By question

========

=> 6y = 10x+y

=> 5y = 10x

=> y = 2x

According to the problem

================

=> x + y = 12

=> x + 2x = 12

=> 3x = 12

=> x = 12/3 = 4

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

Hence the number is (10x+y)

= 10x + 2x = 12x

= 12×4 = 48 (answer)
