Question

Seven more than a two-digit number is equal to two less than the number obtained by reversing the digits. If the sum of the digits is 9. Find the number.

Answer 1

Step-by-step explanation:

TO SOLVE SUCH KIND OF QUESTIONS WE NEED TO KNOW ADDENDS OF 9 .

SO ADDENDS OF 9 ARE (1+8) , (2+7) , (3+6) , (4+5) , (5+4) AND (9+0)

NOW GIVEN THAT 7 MORE THAN THE NUMBER IS TWO LESS THAN THE NUMBER OBTAINED AFTER REVERSING THE DIGITS

SO , 45+7=52

AND REVERSE OF 45 IS 54

NOW 52 IS 2 LESS THAN 54

HENCE , IT IS THE ANSWER AS IT SATISFIES THE GIVEN QUESTION
