Answer» Correct Answer - Option 3 : 59 Given: The given number = 3481 Concept: Calculation skills trick Calculation: Step(1): The unit digit in this number is 1, which can be a unit digit of its square root number such as 1 or 9. Because 1 x 1 is 1 and 9 x 9 is 81. Step(2): Now let us consider the first two digits that is 34 which comes between the squares of 5 and 6 because 25 < 34 < 36 Step(3): We can assume that the ten’s digit of the square root of 3481 is the lowest among the two numbers i.e. 5 Step(4): Now, we need to find among 51 and 59 which is the square root of 3481. Step(5): Since the ten’s digit is 4 and the next number is 5, we need to multiply both the numbers like 5 x 6 = 30 and since 30 is smaller than 34. Step(6): Square root of 3481 will be the greater number among 51 and 59 i.e. 59. ∴ √3481 = 59 |
