Answer:
Step-by-step explanation:Let the digit at tens place be x
And the digital at ones place be y
Thus the no. Is 10x+y
Reversed order is 10y +x
A/Q
X+y = 15
X= 15 -y
And 10x+y -3 = 10y + x
9x - 9y =3
3x - 3y = 1
3 (15 - y) - 3y = 1
y=22/3
X = 23/3
No. = 10×23/3 + 22/3
= (230+22)÷3
= 252÷3
=84
Answer. No. Is 84
