Question

Sum of two digit digit number is 9 when we interchange the digits it is found that resulting new number is greater than the original number by 27 what is the 2 digit number???

Answer 1

the answer is 36 ....l.

Answer 2

'xy' is the two-digit number.
x+y=9
yx-xy=27
There are the following combinations of x+y=9
1+8=92+7=9
3+6=94+5=9
However, only 63-36=27
Hence, the two-digit number, i.e. 'xy'=36.
