ANSWER:-
Given:
The sum of the digits of a two number is 10. The number formed by interchanging the digits is 36 less than the original number.
To find:
Find the original number.
Solution:
Let the digits are R & S.
The original number is 10R+ S.
The reversed number is R + 10S
Given as;
R + S =10
=) S= 10 - R.........(1)
Therefore,
=) (R+10S) - (10R+S)= -36
=) R+10S -10R -S = -36
=) -9R + 9S = -36
=) -R + S = -4
=) -R + 10-R = -4 [using (1)]
=) -2R= -4 -10
=) -2R= -14
=) R= -14/-2
=) R= 7
So,
Putting the value of R in equation (1), we get;
=) S= 10 -7
=) S= 3
Thus,
The original number is 10R + S
=) 10(7) +3
=) 70 +3
=) 73
Hope it helps ☺️
