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
