If each of the digits in the number 92581473 are arranged in ascending order, what will be the difference between the digits, which are fourth from the right and third from the left in the new arrangement?

When Rahul was shifted by three places towards his right side, then he occupies the middle position, i.e., 13th position.

Total number of boys = (10 + 27 - 1)
    = 37 - 1 = 36
So, Rajan's position from the right
= (36 - 10) + 1 = 26 + 1 = 27

In the given series, there are six 9's followed by and preceded by number divisible by 2.

According to question,
Days by Mohan, [17th, 18th or 19th] January
Days by sister, [19th, 20th, 21st or 22nd] January.
Required days is 19th January as it is common in both the groups.

According to above question,
Days by Rajat, June 18 or earlier.
Days by his sister, June 18 or June 19.
Clearly, June 18 is the required day.

After interchanging the first and the last digit, numbers are 984, 145, 456, 359, 387
Hence, second highest number = 456 means 654.

Arranging all the digits in ascending order, we get
489, 145, 456, 359, 378
Hence , lowest number = 145 ? 541

489 ? 484, 541 ? 536, 654 ? 649,
953 ? 948, 783 ? 778
Hence, required difference = 7 - 4
= 3

After interchanging first first and second digit, number are
849, 451, 564, 593, 873.
Hence, third highest number = 593 ? 953

As per the given information C has more amount than only E/B/A. So, it means D > C > E / B / A arrangement can be established.
So, D has maximum amount of money.
