Answer 1

Answer:

66

Step-by-step explanation:

Let the digit at unit place be y

And the digit at ten's place be x

so , this two digit number will be 10x + y.

Sum of the both digits is 12...............( Given )......(1)

but, Both the digits are same............( Given )......(2)

So, according to the given condition.

x+y = 12.............( From the 1st condition.)

x+x = 12..............( From the 2nd condition.)

2x = 12

x = 12/2

so, x = 6

so,the given two digit number is 66.
