Question

The sum of two digit number and the number formed by interchanging it's digit is 110. if 10 is subtracted from the original number. the new number is 4 more than 5 times the sum of the digit of the original number find the original number

Answer 1

Answer:

64

Step-by-step explanation:

Let say number = 10x+y

Interchanged number = 10y+x

Sum = 11x +11y = 110

x +y = 10

10x+y-10 = 4 + 5×(x+y)

10x +y -14 = 5x +5y

5x -4y = 14

4x+4y = 40

9x = 54

x = 6

6+y = 10

y = 4

Number = 64
