Question

The sum of digits of two digit number is 8 and the difference between the number and that formed by reversing the digits is 18. Find the number.
(a) 85
(b) 53
(e) 62
(d) 26​

Answer 1

Answer:

B) 53

Step-by-step explanation:

Let digit In one’s place be ‘x’ and tens place be ‘y’. So x+y=8

Original number => 10x + y

New number => 10y + x

According to statement given,

(10x + y) - (10y + x) = 18

10x + y - 10y - x = 18

9(x-y) = 18

x-y = 2

x + y = 8 So, y = 8 - x

x - y = 2.

x - (8 - x) = 2

x - 8 + x = 2

2x = 10

x = 5

So digit in one’s place is 3 and tens place is 5.
