Directions: Study the following numbers carefully and answer the questions given below: 5836 7469 8251 6293 4172 If in each number first digit is interchanged with second digit and third digit is interchanged with fourth digit after that first digit is interchanged with fourth digit then what would be the difference of highest and second lowest numbers thus formed?

Step-by-step solution

We have, The given sequence = 5836 7469 8251 6293 4172 After interchanging first digit with second digit and third digit with fourth digit, we get: 8563 4796 2815 2639 1427 Now, interchanging first and fourth digit of each of the above number, we get: 3568 6794 5812 9632 7421 Here, the highest and second lowest numbers are ‘9632’ and ‘5812’ Required Difference = 9632 – 5812 = 3820 Hence, the correct answer is option B .
