Answer:
86
Step-by-step explanation:
Let the number be 10x + y. So, the reversed number is 10y + x.
The sum is 154.
So, (10x + y) + (10y + x) = 154
⇒ 11x + 11y = 154
⇒ x + y = 14 ..... (1)
Again, given that ones digit in the original number is 2 less than the tens digit.
So, y = x - 2 ...... (2)
Now, solving (1) and (2) we get,
x + x -2 = 14
⇒ 2x = 16
⇒ x = 8
So, from equation (2), y = x - 2 = 8 - 2 = 6
Therefore, the original number is 10x + y = 10 × 8 + 6 = 86 (Answer)
