Answer 1

Given

Let the number in the tenths place be = X

and ones place = Y

X+Y=9 ---------- 1

X=Y+5 ----------- 2

Substituting the value of X in Eq 1

Y+Y+5=9

2Y=9-5

2Y=4

Y=2

And now Substituting the value of Y in Eq 1

X=2+5

X=7

Required Number 75

Proof:

The reversed number is 45 less than the original

75-27

=45

Hence Proved
