Question

Please solve question no 3.

Answer 1

Let tens digit of number is X

.......Unit digit ........................ is Y

Now Number = X×10 +Y

If digits are reversed

New Number = 10Y+X

ATQ

X-Y= 6.......1

(10X+Y )+ (10Y+X) =110

11X+11Y=110

X+Y= 10 ......................2

Subtracting eq 2 from eq1

X-Y=6

X+Y= 10

2X=16

X=8

Y=8-6

Y=2

SO

The Number is 8×10 +2 = 82

Answer---82
