Answer:
74.
Step-by-step explanation:
Let the number be xy.
Then from the given data
x = y + 3..........(1)
The numerical value of xy is 10x + y so the second equation is
10x + y + 10y + x = 121
11x + 11y = 121 Simplifying:
x + y = 11
x = -y + 11 .........(2) Adding equations (1) and (2):
2x = 14
x = 7
and therefore y = 7 - 3 = 4.
