Question

In a two – digit number the difference between the digits is 3, if the sum of the digits is 15.Find the two - digit number?

• A. 68
• B. 78
• C. 98
• D. 67
• E. None of these

Answer 1

The correct option is E

None of these

Let the ten's digits be x and unit's digit be y

Then, x+y=15 and x-y=3 or y-x=3

Solving x+y=15 and x-y=3, we get : x = 9, y=6

Solving x+y=15 and y-x=3, we get : x=6, y=9

So, the number is either 96 or 69.

Hence, the number cannot be determined
