Question

2. A number consists of two digits whose sum is 8. If 36 is added to the
number, the digits are reversed. Find the number.

Answer 1

Solution :

Let the one number be x and another number be 8 - x.

$\bigstar\: \: \underline{\boldsymbol{According\: to \:the\: Question\:now :}}$

10x + (8 - x) + 36 = 10(8 - x) + x

10x + 8 - x + 36 = 80 - 10x + x

9x + 44 = 80 - 9x

9x + 9x = 80 - 44

18x = 36

x = 2

Therefore,

• One number = x = 2
• Other number = (8 - x) = 8 - 2 = 6
