Question

The sum of the digi
m of the digits of a two-digit number is 11. If the digits are reversed, the new
per is 27 less than the original number. Find the original number.​

Answer 1

Step-by-step explanation:

let the unit digit be X

then ten's digit = 11-x

number formed= 10(11-x) + X = 110-9x

if 27 is subtracted from it number gets reversed so the number formed after subtraction = 9x + 11

now equate both the equations you will get 4 as unit digit and 7 as ten's digit the number will be 74
