Question

A number consists of two digits whose sum is 15 if 27 is subtracted the digits are reversed find the number PLEASE ANSWER STEP BY STEP

Answer 1

Answer:

96

Step-by-step explanation:

Let the digit in the unit place be x. Then, digit in the tens' place = (15-x).

Therefore, the number is 10x+15-x=9x+15.

So, the new number by reversing=10(15-x)+x=150-10x+x=150-9x.

Also, the new number is 9x+15-27=9x-12.

Therefore,

150-9x=9x-12

or, 9x+9x=150+12

or, 18x=162

or, x=162/18

or, x=9

Therefore, the number = 10×9+15-9 = 96

Answer 2

let one digit be x

and ten digit be y

therefore the number is 10y+x

also x+y=15=> v=15-x

10y+x27=10x+y

put y=15-x

10(5-x) +x-27=10x+15-x

x=6

y=9

number=96
