Question

the sum of two digit number is 8 .The number is obtained by interchainging the exceeds by the 18 .find the number
​

Answer 1

Answer:

35

Step-by-step explanation:

Let the no. be 10x+y

Sum of digits = x+y = 8. ...........................(i)

No. obtained by interchanging digits = 10y+x

Given, 10y+x = 10x+y + 18

9y-9x = 18

-x+y = 2. .......................(ii)

Solving (i) and (ii),

y = 5, x = 3

So, number = 35.
