Mr. Ganesh bought 4,500 shares of ABC company at the rate of Rs. 14 each. He sold 3,000 shares at a cost of Rs. 18 each, and then after one week, the price of the share decreased by one-third of its value and he sold the remaining shares. Find the profit or loss made by Mr. Ganesh in the entire transaction considering brokerage charged is negligible.

Step 1: Calculate the total cost of the shares bought by Mr. Ganesh.

Mr. Ganesh bought 4,500 shares at the rate of Rs. 14 each. So, the total cost of the shares = 4,500 * 14 = Rs. 63,000

Step 2: Calculate the total amount Mr. Ganesh got from selling 3,000 shares.

He sold 3,000 shares at a cost of Rs. 18 each. So, the total amount he got = 3,000 * 18 = Rs. 54,000

Step 3: Calculate the new price of the share after it decreased by one-third of its value.

The price of the share decreased by one-third of its value. So, the new price = 14 - (14/3) = Rs. 9.33 (approx)

Step 4: Calculate the total amount Mr. Ganesh got from selling the remaining shares.

He had 4,500 - 3,000 = 1,500 shares left. He sold these at the new price. So, the total amount he got = 1,500 * 9.33 = Rs. 13,995 (approx)

Step 5: Calculate the total amount Mr. Ganesh got from selling all the shares.

The total amount = amount from selling 3,000 shares + amount from selling the remaining shares = 54,000 + 13,995 = Rs. 67,995

Step 6: Calculate the profit or loss made by Mr. Ganesh.

The profit or loss = total amount from selling all the shares - total cost of the shares = 67,995 - 63,000 = Rs. 4,995

So, Mr. Ganesh made a profit of Rs. 4,995 in the entire transaction.
