If in each number, all the three digits are arranged in ascending order, which of the following will be the lowest number?

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

Ascending order 1 2 3 4 5 7 8 9
? Required difference = 5 - 3 = 2

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.

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.

On the basis of give information,
Order of ranking of height in the question of variable nature as it cannot be established whether Harish is taller than Suresh or not. The given information not complete to bring a relationship between Harish and Suresh.
So it cannot be determined who is the shortest.

According to question,
Roshan is taller than Hardik who is shorter than Sushil.
R > Hardik But Hardik < S.
Niza is taller than Harry but shorter than Hardik.
N > Harry But N < Hardik
Sushil is shorter than Roshan.
S < R
Descending order of the heights is as
Roshan > Sushil > Hardik > Niza > Harry.
Therefore, the tallest person is Roshan.
