Answer:
92
Step-by-step explanation:
Let the digit at ones place be x.
Then the digit at tens place is (x+7).
Original number = 10(x+7) + x
= 10x + 70 + x
= 11x + 70
According to question,
the digits at the ones and the tens place are interchanged.
=> New number = 10x + x + 7 = 11x + 7
Also, both the numbers are added,
=> 11x + 70 + 11x + 7 = 121
22x + 77 = 121
22x = 121 - 77
22x = 44
x = 44/22
x = 2
So, Original number = 11x + 70
= 11×2 + 70
= 22 + 70
= 92
Therefore, the original number is 92.
