What is the value of a two digit number?
StatementI. The sum of the digits of the number is 9.
Statement II. The digit at the tens place is 125% of the digit at the unit place.
From I and II Let the number be 10x + y Now, x + y = 9……..(i) ∴ x = 125/100 y = 5/4 y………(ii) From (i) and (ii), we get x = 5, y = 4 ∴ Required number = 54
