Verified Answer
Four friends Rishabh, Keshav, Lavish and Hemang are out for shopping. ...
Let, Rishabh has 'P' amount of money, Keshav has 'Q' amount of money, Lavish has 'R' amount of money, and Hemang has 'S' amount of money.
Therefore, according to the question
P < 3 × Q
R > Q,
S = R - Q
P = 3 × S
Also, Lavish borrows 300 from Rishabh and buys a goggle and Keshav buys a Sleeveless t-shirt after borrowing 100 from Rishabh and is left with no money. Implies that, 
Q = 600 - 100 (Rishabh) = 500
R ≥ 1000 - 300 (Rishabh) ≥ 700
Also, Rishabh buys three shorts means he has a minimum of 1000 (100 + 300 + 3 × 200 = 1000) and the maximum is less than 3Q.
Therefore, 1000 ≤ P < 3Q
1000 ≤ P < 3 × 500
1000 ≤ P < 1500
Since Rishabh has three times the money with Hemang
1000 ≤ 3 × S  < 1500
333 ≤  S  < 500
Hence, Hemang could buy a sleeper with his own money.

Four friends Rishabh, Keshav, Lavish and Hemang are out for shopping. ...
To solve this problem, let's analyze the given information step by step:

1) Rishabh has less money than three times the amount that Keshav has.
2) Lavish has more money than Keshav.
3) Hemang has an amount equal to the difference of amounts with Keshav and Lavish.
4) Rishabh has three times the money with Hemang.

Let's assume the amount of money Keshav has as 'x'.

1) Rishabh has less money than three times the amount that Keshav has:
Rishabh's money = 3x - y (where y is the amount of money Rishabh has)

2) Lavish has more money than Keshav:
Lavish's money = x + z (where z is the amount of money Lavish has)

3) Hemang has an amount equal to the difference of amounts with Keshav and Lavish:
Hemang's money = x + z - x = z

4) Rishabh has three times the money with Hemang:
3x - y = 3z

From the given information, we can deduce the following:

Rishabh buys three shorts, each costing 200. So, the amount spent by Rishabh is 200 * 3 = 600.

Lavish borrows 300 from Rishabh and buys a goggle costing 1000. So, Lavish now has z - 300 - 1000 = z - 1300.

Keshav buys a Sleeveless t-shirt after borrowing 100 from Rishabh. So, Keshav's remaining money is x - 100 - 600 = x - 700.

From the given information, we know that Rishabh has three times the money with Hemang. So, Rishabh's remaining money after buying three shorts is y - 600.

Now, let's put these values into the equations we deduced earlier:

3x - y = 3z (equation 1)
z - 1300 = x - 700 (equation 2)
y - 600 = 3z (equation 3)

Solving these equations, we get:
z = 200
x = 600
y = 1200

Hemang's money is equal to z, which is 200. Therefore, Hemang can buy the costliest item with his own money, which is a sleeper priced at 400.

Hence, the correct answer is option 'B' - A sleeper.
