Directions: Study the following numbers carefully and answer the questions given below:
5836 7469 8251 6293 4172
5836 7469 8251 6293 4172
If the digits of all the numbers are to be arranged in ascending order within the number from right to left then the numbers thus formed are to be arranged in descending order from left to right then what would be the sum of second digit of third number from left end and third digit of fourth number from right end?
Options
- A12
- B10
- C7
- D9
Correct answer
D. 9
Step-by-step solution
We have,
9764 9632 8653 8521 7421
The given sequence = 5836 7469 8251 6293 4172
After arranging the digits of all the numbers in ascending order within the number from right to left, we get:
8653 9764 8521 9632 7421
After, arranging the newly formed in descending order from left to right, we get:
9764 9632 8653 8521 7421
Here, third number from left end is ‘8653’ and second digit of ‘8653’ is ‘6’.
And, fourth number from right end is ‘9632’ and third digit of ‘9632’ is ‘3’.
Required Sum = 6 + 3 = 9
Hence, the correct answer is option D.
