Question

A 2 digit number is 6 more than 4 times the sum of its digit. If 27 is added to the number, its digits are reversed. Find the number ​

Answer 1

Answer:

Step-by-step explanation:

Let the two digit number be 10x + y.

According to question, 10x+y+27=10y+x(no.formed by reversing its digits)

10x+y-10y-x+27=0

9x-9y+27=0

x-y+3=0(divide the equation with 9)..........(1)

4(x+y)+6=10x+y

4x+4y-10x-y+6=0

-6x+3y+6=0

2x-y-2=0...........(2)

Solve 1 and 2

x-2x+3+2=0

x=5

Now in (1)

5-y+3=0

y=8

The two digit number is 58.

Hope it helps you.
